Song, Jinming published the artcileReversible Multilevel Stimuli-Responsiveness and Multicolor Room-Temperature Phosphorescence Emission Based on a Single-Component System, Recommanded Product: 1-Bromooctane, the publication is Angewandte Chemie, International Edition (2022), 61(29), e202206157, database is CAplus and MEDLINE.

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.

Liquid-crystalline D-A dyads and A-D-A triads, based on the chem. association of electron-donor (D) triphenylene discogens and electron-acceptor (A) perylene/benzoperylene diimides, have been synthesized by the Pd-catalyzed Sonogashira coupling/DBU-promoted cyclization reactions tandem. These mol. heterojunctions spontaneously self-organize into columnar hexagonal (Col_hex) or/and rectangular (Col_rec) mesophases, over broad temperature ranges including room temperature, with the antagonist moieties segregated into alternated homo-mol. (homolithic) stacks within mixed columns. Their intramol. electron and energy transfers have been studied by UV/Vis absorption and fluorescence emission spectroscopies. Due to photo-induced electron transfer between donor and acceptor units, fluorescence quenching is systematically observed for all the dyads and triads. This study further reveals that perylenediimide is a stronger electron acceptor than the larger benzoperylenediimide building block. D. function theory calculations of their mol. structures and HOMO-LUMO energy levels and gaps support the exptl. results and demonstrate that these donor-acceptor systems have potential applications in various optoelectronic devices.

Xu, Feng published the artcileDeveloping versatile and highly selective chemosensor for amines detection based on bis-thiophene methane containing cyclopalladated compounds, Recommanded Product: 1-Bromooctane, the publication is Sensors and Actuators, B: Chemical (2022), 131561, database is CAplus.

Cyclopalladated compounds (CPCs) have special properties due to its internal multiple conjugate planes in their structure. Herein, a series of bis-thiophene methane-pyridine-Schiff base derivatives (L_n) and their CPCs (L_n-Pd) as monomers were prepared All cyclopalladated monomers showed extreme sensitivity to organic amines in both solution and vapor states. The results of structural anal. manifested that the complexes before and after alkali-treated have a relationship between monomer and dimer. Furthermore, the base-induced mechanism was expounded. To take full advantage of this feature, we utilized the monomer containing tetraphenylethylene (L₄-Pd) to detect organic amines in solution, which showed excellent sensitivity toward triethylamine and diethylamine with the limit of detection of 41 nM and 104 nM, resp. Then, the L₄-Pd coated labels were exposed to amine vapors at ppm level, which showed visible color variation in n-butylamine, ethylenediamine, diethylamine, and cyclohexylamine atm. It is suggesting that the materials have potential applications to detect organic amines in solution at trace anal. and a solid colorimetric chemosensor for organic amine vapors.

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

Unny, Divya published the artcileStarburst configured imidazole-arylamine organic sensitizers for DSSC applications, Recommanded Product: 1-Bromooctane, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2022), 113735, database is CAplus.

In this study, special consideration was given to the design and synthesis of imidazole-arylamine-based organic sensitizers with three arylamine donors (Carbazole, Triphenylamine and Phenothiazine) paired with cyanoacrylic acid acceptor to form D-D-A architecture. Phenothiazine-imidazole dye (PZIM) was found to be the best for DSSC applications in the D-D-A set. Hence, we further extended the conjugation of PZIM dye by three different spacers such as benzene (PZIMBe), thiophene (PZIMTh), and furan (PZIMFu) having different resonance energies, which resulted in the design of D-D-π-A. We have carried out the photo-phys., electrochem., and photovoltaic performance for these six dyes. The PZIM, PZIMTh and PZIMFu dyes were identified as the efficient among the six with an average power conversion efficiency of 7.0%, 7.10% and 7.30%, resp. Thiophene and furan outperformed benzene spacer as the best linkers in the D-D-π-A configuration. Grafting the bulky imidazole moiety onto the arylamine donor is considered to be a promising approach for tuning photovoltaic parameters by increasing the electron richness of the main electron donor core, increasing solubility, and suppressing aggregation.

Tang, Min-Min published the artcileRole of Rim Functions in Recognition and Selectivity of Small-Molecule Guests in Water-Soluble Cavitand Hosts, Safety of 1-Bromooctane, the publication is Chemistry – An Asian Journal (2022), 17(15), e202200466, database is CAplus and MEDLINE.

Groups on the upper rim of cavitands can play major roles in the recognition of small mols. Water-soluble deep cavitands 1, 2 or 3 bearing the walls upper rim of imidazole, urea, and Me urea, resp., were synthesized and characterized as hosts of small-mol. guests. The vase forms of 1 or 2 are stabilized through H-bonding to solvent water mols. between adjacent walls. Various small alkyl organic mols. – alcs., halides, cycloalkane derivatives and heterocycles – are efficiently bound in 1. For n-alcs. (C5 to C12), the -OH end is fixed at the upper rim and the alkyl parts are in the hydrophobic cavity. The longer alc. guests (C7-C12) show coiling. Cycloalkane guests rotate rapidly on all 3 axes within the host cavity, while heterocycles show orientations placing their heteroatoms near the cavitand rim. Competition studies between alkyl chlorides, bromides and iodides showed preference for binding of iodides in 1. Competition between cavitands for hexyl halide guests halide showed the order 2>1>3.

Cavieres, Jenifer published the artcileIonanofluids based on ionic liquid mixtures, a new approach as an alternative material for solar energy storage, Recommanded Product: 1-Bromooctane, the publication is Journal of Molecular Liquids (2022), 118677, database is CAplus.

Hybrid materials based on ionic liquids (ILs) known as Ionanofluids (INFs) have shown exciting improvements in their thermophys. properties compared to their base fluids (BF). Within this group, INFs obtained using mixtures of ionic liquids as BFs have been virtually ignored until now. In this work, INFs composed of two equimolar mixtures of ILs, [Omim][PF₆] + [Odmim][PF₆] and [Omim][PF₆] + [Odmim][BF₄] as base fluids and Multiwalled Carbon Nanotubes (MWCNTs) with weight percentages of 0.04, 0.06, 0.08, and 0.1 wt% were elaborated. Furthermore, the thermophys. properties of our proposed new materials were evaluated and compared to conventional materials currently used in solar energy storage systems. It was shown that the heat capacity (Cp) reaches increases of up to 3.7 and 3.2 times that of nitrated salts and the com. fluid Therminol VP-1, which translates into a 9.4% and 284% higher thermal storage d. (E), resp., and even lower thermal diffusivity (α), which supports the preliminary idea of using these new materials for energy storage.
