Wan, Ruomeng;Buss, Joshua A.;Horak, Kyle T.;Agapie, Theodor research published 《 A hemilabile diphosphine pyridine pincer ligand: σ- and π-binding in molybdenum coordination complexes》, the research content is summarized as follows. Mo compounds supported by a hemilabile pyridine diphosphine pincer ligand were synthesized. The ligand demonstrates variable binding modes, adapting to the electronic and geometric requirements of the metal center. In Mo⁰ and Mo^II polycarbonyl complexes, coordination through the σ-donating pyridine nitrogen lone pair is observed Upon oxidative group transfer with anionic azide, a Mo^IV nitride compound is formed, accompanied by a change in the ancillary ligand binding mode to the pyridine π-system. The σ-coordination was restored by subsequent functionalization of the nitride moiety with either silyl electrophiles or protons. Protonation results in redox disproportionation with concomitant nitride functionalization. Characterization by single crystal x-ray diffraction, NMR, and IR spectroscopy is discussed.

2-Bromophenylboronic acid, also known as 2-Bromophenylboronic acid, is a useful research compound. Its molecular formula is C6H6BBrO2 and its molecular weight is 200.83 g/mol. The purity is usually 95%.
2-Bromophenylboronic acid is a glucose monitoring agent that has a ruthenium complex with an acidic environment. The nitro group and the amines are in close proximity to the boron center, and this proximity leads to a high nucleophilic character of the molecule. This reactivity allows 2-bromophenylboronic acid to be used as a fluorescence probe for acidic environments. 2-Bromophenylboronic acid also inhibits secretase enzymes, which are involved in Alzheimer’s disease and other neurodegenerative disorders. It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., 244205-40-1.

Waltemate, Jana;Ivanov, Igor;Ghasemi, Jahan B.;Aghaee, Elham;Daniliuc, Constantin Gabriel;Mueller, Klaus;Prinz, Helge research published 《 10-(4-Phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and related compounds: Synthesis, antiproliferative activity and inhibition of tubulin polymerization》, the research content is summarized as follows. As part of our continuing search for potent inhibitors of tubulin polymerization, two novel series of 42 10-(4-phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and N-benzoylated acridones were synthesized on the basis of a retrosynthetic approach. All newly synthesized compounds were tested for antiproliferative activity and interaction with tubulin. Several analogs potently inhibited tumor cell growth. Among the compounds tested, 10-(4-(3-methoxyphenyl)piperazine-1-carbonyl)acridin-9(10H)-one (17c, I) exhibited excellent growth inhibitory effects on 93 tumor cell lines, with an average GI₅₀ value of 5.4 nM. We were able to show that the strong cytotoxic effects are caused by disruption of tubulin polymerization, as supported by the EBI (N,N’-Ethylenebis(iodoacetamide)) assay and the fact that the most potent inhibitors of cancer cell growth turned out to be the most efficacious tubulin polymerization inhibitors. Potencies were nearly comparable or superior to those of the antimitotic reference compounds Closely related to this, the most active analogs inhibited cell cycling at the G2/M phase at concentrations down to 30 nM and induced apoptosis in K562 leukemia cells. We believe that our work not only proves the excellent suitability of the acridone scaffold for the design of potent tubulin polymerization inhibitors but also enables synthetic access to further potentially interesting N-acylated acridones.

Walker, Rebecca;Pociecha, Damian;Faidutti, Camilla;Perkovic, Eva;Storey, John M. D.;Gorecka, Ewa;Imrie, Corrie T. research published 《 Remarkable stabilisation of the intercalated smectic phases of nonsymmetric dimers by tert-butyl groups》, the research content is summarized as follows. The synthesis and characterization of two groups of nonsym. dimers, the 1-(4-cyanobiphenyl-4′-yloxy)-ω-(4-alkylbenzylidene-4′-oxy)alkanes and the 1-(4-cyanobiphenyl-4′-yl)-ω-(4-alkylbenzylidene-4′-oxy)alkanes, are reported. The length and parity of the flexible spacer are varied. The tert-Bu homologues show higher m.ps. than the corresponding sec-Bu or Bu substituted dimers and suggesting that chain branching improves packing efficiency within the crystalline structure. The branched chain homologues have a stronger tendency to exhibit smectic phases than the n-butyl-substituted dimers and are exclusively smectic for longer spacers. A comparison of the nematic-isotropic transition temperatures (TNI) for the dimers and containing the different terminal chains is possible for one set of materials, and reveals a large reduction in TNI on passing from the Bu to sec-butyl-substituted, but a much smaller decrease on changing sec-Bu for tert-Bu. A different trend is observed for the smectic A-isotropic transition temperatures for which the tert-Bu substituted dimers and show a higher value than the corresponding sec-Bu homolog, and only marginally lower than that of the n-butyl-substituted dimers. This surprising behavior is interpreted in terms of the ability of the tert-Bu group to pack more efficiently into the intercalated smectic A phase as the spacer length increases.

Walker, Rebecca;Majewska, Magdalena;Pociecha, Damian;Makal, Anna;Storey, John MD;Gorecka, Ewa;Imrie, Corrie T. research published 《 Twist-Bend Nematic Glasses: The Synthesis and Characterisation of Pyrene-based Nonsymmetric Dimers》, the research content is summarized as follows. A selection of pyrene-based liquid crystal dimers I [n = 5, 6, 8, etc.] , II [n = 5, 6, 11, etc.] and III were prepared, containing either methylene-ether or diether linked spacers of varying length and parity. All the diether linked materials, II, exhibited conventional nematic and smectic A phases, with the exception of II [n = 11] which was exclusively nematic. The methylene-ether linked dimer, I with an even-membered spacer (n=5) was solely nematogenic, but odd-members (n=6, 8, 10) exhibited both nematic and twist-bend nematic phases. Replacement of the cyanobiphenyl fragment by cyanoterphenyl giving III, gave elevated melting and nematic-isotropic transition temperatures, and SmA and SmC_A phases were observed on cooling the nematic phase. Intermol. face-to-face associations of the pyrene moieties drove glass formation, and all these materials had a glass transition temperature at or above room temperature The stability of the glassy twist-bend nematic phase allowed for its study using AFM, and the helical pitch length, P_TB, was measured as 6.3 and 6.7 nm for I [n = 6, 8] , resp. These values were comparable to the shortest pitch of a twist-bend nematic phase measured to date.

Wagner, Jakub;Zimmermann Crocomo, Paola;Kochman, Michal Andrzej;Kubas, Adam;Data, Przemyslaw;Lindner, Marcin research published 《 Modular Nitrogen-Doped Concave Polycyclic Aromatic Hydrocarbons for High-Performance Organic Light-Emitting Diodes with Tunable Emission Mechanisms》, the research content is summarized as follows. Although bowl-shaped N-pyrrolic polycyclic aromatic hydrocarbons (PAHs) can achieve excellent electron-donating ability, their application for optoelectronics is hampered by typically low photoluminescence quantum yields (PLQYs). To address this issue, we report the synthesis and characterization of a series of curved and fully conjugated nitrogen-doped PAHs. Through structural modifications to the electron-accepting moiety, we are able to switch the mechanism of luminescence between thermally activated delayed fluorescence (TADF) and room-temperature phosphorescence (RTP), and to tune the overall PLQY in the range from 9% to 86%. As a proof of concept, we constructed solid-state organic light-emitting diode (OLED) devices, which has not been explored to date in the context of concave N-doped systems being TADF/RTP emitters. The best-performing dye, possessing a peripheral trifluoromethyl group adjacent to the phenazine acceptor, exhibits yellow to orange emission with a maximum external quantum efficiency (EQE) of 12%, which is the highest EQE in a curved D-A embedded N-PAH to date.

Vyas, Akshay;Koshti, Rohit R.;Patel, H. N. research published 《 Effect of terminal metamers and homologous with imine and ester groups on mesomorphism and their DFT study》, the research content is summarized as follows. Three liquid crystalline series with different terminal chains I [R = Me, Et, Pr, etc.; R¹ = (CH₂)₂OCH₂Me, CH(Me)CH₂OMe, (CH₂)₂O(CH₂)₃Me] have been prepared, where two of the series are metamer of each other, and all three series are homologues of each other in context to the terminal chain. All the homologues prepared were found to be enantiotropically mesogenic and screened under a polarizing optical microscope (POM). Differential scanning calorimetry (DSC) technique was used to obtain thermograms of phase transition, enthalpy and entropy change. Characterization of all homologues was carried out by means of standard spectroscopic methods; IR, proton magnetic resonance and UV spectroscopy. Series I [R¹ = CH(Me)CH₂OMe] exhibited polymorphism as of smectic C, smectic A and nematic mesophases, while series I [R¹ = (CH₂)₂OCH₂Me, (CH₂)₂O(CH₂)₃Me] exhibit only smectic A and nematic mesophases. The geometry of all homologues was obtained using DFT calculation, and the effect of the twist angle of the aromatic ring on mesomorphism was examined The effect of branching and length of the broken alkoxy terminal chain on the type of the mesophase was studied by comparing the terminal chain homologues. The prepared series was also compared with four structurally similar compounds to understand the effect of the relative position of groups and the effect of mol. length on thermal stability and mesophase length.
