colorimetric chiral sensor material consisting of three different functional sites such as chromophore (2,4‐dinitrophenylazophenol dye), binding site (crown ether), and chiral barrier (3,3′‐diphenyl‐1,1′‐binaphthyl group) was prepared and applied to the recognition of the two enantiomers of primary amino alcohols and amines. Among five primary amino alcohols and two primary amines tested, the two enantiomers
一种新的比色手性传感器材料,它由三个不同的功能位点组成,例如发色团(2,4-二硝基苯基偶氮苯酚染料),结合位点(冠醚)和手性屏障(3,3'-二苯基-1,1'-联萘基)制备并用于识别伯氨基醇和胺的两种对映体。在五个伯氨基醇以及两个伯胺测试,苯丙氨醇的两种对映体显示出在最大吸收波长(Δλ最高差最大= 43.5纳米)和结合常数(ķ小号/ ķ ř与比色手性传感器材料络合后,其分子量为2.51),因此,苯丙氨醇的两种对映异构体之间的色差可以清楚地区分。手性,2011年。©2010 Wiley-Liss,Inc.。
