development of sterically induced polar order in liquid‐crystalline (LC) soft matter. Three series of weakly bent molecules derived from 4‐cyanoresorcinol as the bent core unit with laterally fluorinated azobenzene wings have been synthesized, and the effects of the position of fluorine substitution, alkyl‐chain length, and temperature on the LC self‐assembly and polar order were studied. In the LC phases

Phosphonium-based ionic liquids: Economic and efficient catalysts for the solvent-free cycloaddition of CO2 to epoxidized soybean vegetable oil to obtain potential bio-based polymers precursors
these ionicliquids was compared to the widely used and benchmark catalyst in CO2 cycloaddition to epoxides reaction, namely tetrabutylammonium bromide at different reaction conditions. The influence of some reaction parameters such as temperature, CO2 pressure, reaction time and catalyst amount was studied. It has been found that the solubility of the prepared ionicliquids in the reaction media (epoxidized
一系列基于鏻的离子液体以一种简单的方式从廉价的原料中一步制备。所制备的离子液体已成功地在 CO 2与环氧化大豆油的无溶剂环加成反应中作为催化剂进行测试,以获得碳酸豆油,该油可潜在地用作生物基聚合物合成中的生物单体。将这些离子液体的催化性能与CO 2环加成到环氧化物反应中广泛使用的基准催化剂,即在不同反应条件下的四丁基溴化铵进行了比较。温度、CO 2等反应参数的影响对压力、反应时间和催化剂用量进行了研究。已经发现,制备的离子液体在反应介质(环氧化大豆油)中的溶解度是限制一些合成离子液体催化性能的关键因素。所有制备的离子液体都表现出比基准催化剂更高的热稳定性,其中三种表现出优异的催化性能。十二烷基三苯基溴化鏻 ( 5 )在转化率和选择性方面获得了最佳结果,在160 ºC和40 bar CO 2 条件下反应5 小时后,几乎完全转化 ( 99.8% ) 和出色的选择性 ( 84.0% )。 . 与文献中报道的那些相比,在无溶剂CO

Disclosed are acyclic nucleoside prodrugs with improved metabolic stability and oral bioavailability. In general, the prodrugs are derivatives of acyclic nucleoside phosphonates containing a lipid-like moiety that can increase oral absorption and subsequent stability in the liver and plasma. Preferably, the lipid-like moiety can resist enzyme-mediated ω-oxidation, such as ω -oxidation catalyzed by cytochrome P450 enzymes. Also disclosed are pharmaceutical formulations of the acyclic nucleoside prodrugs. The acyclic nucleoside prodrugs and pharmaceutical formulations thereof can be used to treat viral infections, such as HIV infections, and/or viral-associated cancer, such as HPV-associated cancers.

ligands bind to Ag(I) ions. The molecular structures of [Ag2(1)2](ClO4)2 and [Ag2(2)2](ClO4)2 (1, 9-ethyl-1,N6-ethenoadenine; 2, 9-propyl-1,N6-propylenoadenine) confirm that dinuclear complexes with short Ag···Ag distances are formed (3.0256(3) and 2.984(1) Å, respectively). The structural motif can be extended to divalent metal ions, as was shown by determining the molecular structure of [Cu2(1)2(CHO2)2(OH2)2](NO3)2·2H2O
