previously reported that an optically active cyclic amide consisting of a helical chiral 1,12-dimethylbenzo[c]phenanthrene-5, 8-dicarboxylic acid forms a stable monolayer on the water surface, and that the monolayer can be transferred on a solid support giving optically active Langmuir-Blodgett (LB) films. In this study, several related amides were synthesized, and their monolayer behaviors were investigated
我们以前曾报道过,由螺旋手性1,12-二甲基苯并[ c ]菲-5,8-二羧酸组成的旋光环状酰胺在水表面形成稳定的单层,并且该单层可以转移到固体载体上得到光学活性的朗缪尔-布洛杰特(LB)膜。在这项研究中,合成了几种相关的酰胺,并对其单层行为进行了研究,以期制备具有官能团的光学活性LB膜。结果表明,环状酰胺结构和环己基部分对于在水表面形成稳定的单分子层至关重要。仲酰胺的N-烷基化不会严重影响单层的形成,而手性LB膜可通过N,N获得环酰胺的-双(3-巯基丙基)衍生物。
