We report the design of novel medium bandgap nonfullerene small mol. acceptor NFSMA SPS-TDPP-2CNRh with A₂-π-A₁-π-A₂ architecture, with the mol. engineering of this material comprising a strong electron-accepting backbone unit DPP (A₁) as the acceptor, which is attached to the dicyanomethylene-3-hexylrhodanine (A₂) acceptor via a furan (π-spacer) linker. We systematically studied its structural and optoelectronic properties. The incorporation of dicyanomethylene-3-hexylrhodanine and furan enhance the light absorption and electrochem. properties by extending π-conjugation and is anticipated to improve V_OC by decreasing the LUMO level. The long alkyl chain units were responsible for the better solubility and aggregation of the resultant mol. Binary BHJ-OSCs constructed with polymer P as the donor and SPS-TDPP-2CNRh as the acceptor resulted in a PCE of 11.49% with improved V_OC = 0.98 V, J_SC = 18.32 mA/cm², and FF = 0.64 for P:SPS-TDPP-2CNRh organic solar cells. A ternary solar cell device was also made using Y18-DMO and SPS-TDPP-2CNRh as acceptors having complementary absorption profiles and polymer P as the donor, resulting in a PCE of 15.50% with improved J_SC = 23.08 mA/cm², FF = 0.73, and V_OC = 0.92 V for the P:SPS-TDPP-2CNRh:Y18-DMO solar cell. The ternary OSCs with SPS-TDPP-2CNRh as the host acceptor in the P:Y18-DMO binary film were shown to have improved PCE values, which is mainly attributed to the effective photoinduced charge transfer through multiple networks and the use of excitons from SPS-TDPP-2CNRh and Y18-DMO. Moreover, in the ternary BHJ active layers, the superior stable charge transport that was observed compared to the binary counterparts may also lead to an increase in the fill factor. These results demonstrate that combining medium bandgap and narrow bandgap NFSMAs with a wide bandgap polymer donor is a successful route to increasing the overall PCE of the OSCs via the ternary BHJ concept.

This paper described the corrosion inhibiting action of four new imidazolium-derived ionic liquids (ILs) I [X = H, Me, Cl, NO₂]. Elements anal., IR, TGA, ¹H-¹³C NMR, XRD and HSQC-NMR were used to confirm the mol. formula of ILs. The corrosion suppressive effectiveness was calculated using loss of mass and electrochem. experiments and ranged from 53 to 96%. Their adsorption on a steel substrate was precisely characterized using the Langmuir isotherm. Gibbs free energies vary from – 35.24 kJ mol^-1 to – 41.82 kJ mol^-1, indicating that ILs were adsorbing via physi-chemisorption scenario. SEM/EDX and FTIR were used to validate the process of adsorption of ionic liquids

Abdelhafiz, Fatma M. published the artcileDesigning of quaternized hyperbranched polyamidoamines dendrimers: Surface activity, pharmaceutical efficacy, and safety approach, HPLC of Formula: 143-15-7, the publication is Journal of Drug Delivery Science and Technology (2022), 102929, database is CAplus.

The low solubility of the drug considers a major challenge for pharmaceutical formulation of both oral and parenteral products. In this work various generations of cationic hyperbranched polyamidoamine (PAMAM) quaternary ammonium salt dendrimers terminated with amine end groups were synthesized. The pharmaceutical application of these quaternized cationic surfactants ended with amine end groups and those ended with ester end groups which prepared in an earlier study were investigated. These dendrimers were compared as solubilizing agents for coenzyme Q10 (poorly soluble drug) and the dendrimers that showed high solubilizing potential (G_2.5 C₈, G_2.5 C₁₂) were selected to be evaluated as a dendrimer in dissolution study for coenzyme Q10 or Ledipasvir drug. In our investigation a comparison between four dissolution media with different surfactants namely, G_2.5 C₈, G_2.5 C₁₂, CTAB and Labrasol used for the dissolution test of Q10 was carried out. The results revealed that % Q10 released after 4 h was 86.7, 70.5, 43 and 10.5% for these dissolution media, resp. These results indicated the priority of the synthesized cationic surfactants than the known com. cationic surfactant (CTAB) or than Labrasol as recommended surfactant in previous lectures. Therefore, the profiles of the ledipasvir dissolution in the three-dissolution media G_2.5 C₈, G_2.5 C₁₂ and FDA surfactant (1.5% tween 80 and 0.0075 mg/mL Butylated Hydroxytoluene (BHT)) are similar. The obtained results emphasized that the new surfactants can be used as alternative to FDA surfactant in the dissolution media of Ledipasvir. Eventually, the toxicity study was performed for two selected compounds from the prepared dendrimers, and these compounds were proved to be safe.

Sommers, Kyle J. published the artcileQuaternary Phosphonium Compounds: An Examination of Non-Nitrogenous Cationic Amphiphiles That Evade Disinfectant Resistance, Application In Synthesis of 143-15-7, the publication is ACS Infectious Diseases (2022), 8(2), 387-397, database is CAplus and MEDLINE.

Quaternary ammonium compounds (QACs) serve as mainstays in the formulation of disinfectants and antiseptics. However, an over-reliance and misuse of our limited QAC arsenal has driven the development and spread of resistance to these compounds, as well as co-resistance to common antibiotics. Extensive use of these compounds throughout the COVID-19 pandemic thus raises concern for the accelerated proliferation of antimicrobial resistance and demands for next-generation antimicrobials with divergent architectures that may evade resistance. To this end, we endeavored to expand beyond canonical ammonium scaffolds and examine quaternary phosphonium compounds (QPCs). Accordingly, a synthetic and biol. investigation into a library of novel QPCs unveiled biscationic QPCs to be effective antimicrobial scaffolds with improved broad-spectrum activities compared to com. QACs. Notably, a subset of these compounds was found to be less effective against a known QAC-resistant strain of MRSA. Bioinformatic anal. revealed the unique presence of a family of small multiresistant transporter proteins, hypothesized to enable efflux-mediated resistance to QACs and QPCs. Further investigation of this resistance mechanism through efflux-pump inhibition and membrane depolarization assays illustrated the superior ability of P6P-10,10 to perturb the cell membrane and exert the observed broad-spectrum potency compared to its com. counterparts. Collectively, this work highlights the promise of biscationic phosphonium compounds as next-generation disinfectant mols. with potent bioactivities, thereby laying the foundation for future studies into the synthesis and biol. investigation of this nascent antimicrobial class.

Zang, Yu published the artcileSynthesis and Oxygen Permeation of Well-Defined Multistranded Copolymers from Monomers Having Two Different Polymerizable Groups, Synthetic Route of 143-15-7, the publication is Macromolecules (Washington, DC, United States) (2022), 55(13), 5699-5710, database is CAplus.

Four multistranded copolymers were synthesized by two-step selective polymerization of monomers having an acetylene and two olefins. Their second main chains, which were formed at the postpolymn. between the olefin groups in the template acetylene polymers, are categorized into two types, i.e., helical conformations along with the conformations of their template helical polymers and nonhelical conformations parallel to the direction of the main chain of their precursor polymers. The numbers of the strands are two, four, and seven when supramol. strands by hydrogen bonds are included. Since the copolymers were all soluble, they could be fully characterized and fabricated to self-standing membranes. The conversions of the postpolymns. were high. The degree of the postpolymn. could be controlled by changing conditions. Oxygen permselectivies of these multistranded copolymers were better than the corresponding template polymers. The more the number of the strands was, the higher their oxygen permselectivity showed.

Gu, Jilong published the artcileAnhydrous proton conduction in protic ionic liquid crystals formed by 1-alkyl-3H-imidazolium hydrogen sulfates, Related Products of bromides-buliding-blocks, the publication is Ionics (2022), 28(5), 2293-2300, database is CAplus.

Dynamic self-assembly of liquid crystals favors the formation of hydrogen bond networks essential for anhydrous proton conduction. To endow liquid crystals with inherently exchangeable protons for proton conduction, protic 1-alkyl-3H-imidazolium hydrogen sulfates ([C_nIm][HSO₄]) with different lengths of alkyl chains are synthesized. Interdigitated smectic A_d (S_Ad) liquid crystal phases are observed for [C_nIm][HSO₄], in which the protic ionic pairs aggregate into lamellas. Electrochem. characterization reveals that the anhydrous proton conductivity of [C_nIm][HSO₄] reaches up to 5.3 mS cm^-1 in the S_Ad phase. The single fuel cells fabricated from the [C_nIm][HSO₄]@PVDF supported membranes exhibit a peak power d. of 2.6 mW cm^-2 at 130 °C under non-humidified conditions. It was the enriched lamellar hydrogen bond networks formed by the protic ionic pairs that contribute to the anhydrous proton conduction. The protic ionic liquid crystals possess a great potential to construct electrochem. devices involving anhydrous proton conduction.

There are limited reports about the transformation of pure organic room-temperature phosphorescence (RTP) materials with multilevel stimuli-responsiveness at different RTP emission wavelengths under external stimuli. It is difficult to ensure efficient intersystem crossing (ISC) in different states of a single-component system. This research reports the conversion of the organic single-component small mol. 1,2-bis(4-alkoxyphenyl)ethane-1,2-dione (N-BOX) with multilevel stimuli-responsiveness between high-efficiency blue and yellow RTP by grinding or thermal annealing N-BOX crystals. The RTP emission of N-BOX in the crystalline state was easy to adjust by external stimuli (grinding or thermal annealing) due to its non-compact packing, which led to a phase transition and generated unique multilevel stimuli-responsiveness. In particular, the RTP quantum yield of 7-BOX with multilevel stimuli-responsiveness reached 68.4%, which provides an opportunity for regulation of smart optical materials based on pure organic RTP.

Isa Ziembowicz, Francieli published the artcileThermodynamics of aggregation and modulation of Rheo-Thermal properties of hydroxypropyl cellulose by imidazolium ionic liquids, Application of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 119314, database is CAplus.

Mixtures based on cellulose derivatives/ionic liquids (ILs) are potential viscosity modifiers for enhanced oil recovery (EOR). This paper investigates the thermodn. of monocationic imidazolium ionic liquids (1-alkyl-3-methylimidazolium bromide, CnMIMBr) aggregation with hydroxypropyl cellulose (HPC) in the dilute regime and the modulation of its rheol. and thermal properties in the semi-dilute regime. The outcomes showed that binding occurs by hydrophobic interactions between the alkyl chain of ILs and hydroxypropyl group on HPC and by ion-dipole interactions, and it is driven by entropy. The addition of ILs produced a significant increase in the HPC solutions viscosity, which depends on the concentration and alkyl chain length of the ILs (n = 10, 12, 14, 16). Moreover, the presence of ILs produces an effect salt-in delaying the HPC phase separation These findings highlight the role of ILs on the rheol. and thermal properties of HPC, opening new possibilities for the design of new complex mixtures

Nakum, Kiran J. published the artcileThe influence of lateral hydroxyl group and molecular flexibility on the mesogenic behavior of a new homologous series based on thiophene-chalcone: Synthesis, characterization, crystal structure and DFT study, Name: 1-Bromododecane, the publication is Journal of Molecular Structure (2022), 132891, database is CAplus.

A new homologous series of rod shaped calamite liquid crystals, I [R = Et, decyl, octadecyl, etc.] based on thiophene-chalcone was prepared by condensation of 2-hydroxy-4-n-alkoxybenzaldehydes (n = 2 to 8, 10, 12, 14, 16, 18) with (E)-1-(4-aminophenyl)-3-(thiophen-2-yl)prop-2-en-1-one. FT-IR, ¹H NMR, ¹³C NMR and mass spectroscopy were used to characterize synthesized compds I. The liquid crystal behavior of all synthetic compounds I was investigated using Differential Scanning Calorimeter (DSC) and Polarizing Optical Microscope (POM). Lower members of the homologous series, n-heptyloxy to n-dodecyloxy , were nematogenic, and higher members, n-tetradecyloxy to n-octadecyloxy , were smectogenic, whereas n-ethoxy to n-pentyloxy derivatives were non-mesogenic, and n-hexyloxy exhibited monotropic nematic phase. The n-pentyloxy derivative crystallized under monoclinic, space group P2/c with unit cell dimensions a = 16.1723(9) Å, b = 5.8603(3) Å, c = 22.4320(12) Å, β = 100.153(2) , V = 2092.69(9) Å3. The ethoxy derivative was subjected to DFT (d. functional theory) level computations and complete geometric optimization utilizing B3LYP/6-311G (d, p) basis sets and results were compared with structurally similar compound
