Liquid-crystalline dendrons carrying either a thiol or disulfide function which display nematic, smectic A, columnar, or chiral nematic phases have been synthesized. Their mesomorphic properties are in agreement with the nature of the mesogenic units and structure of the dendrons. The first-generation poly(aryl ester) dendron containing two cyanobiphenyl mesogenic units was used to functionalize gold
已经合成了具有硫醇或二硫键功能的液晶树突,其显示向列相,近晶A相,柱状或手性向列相。它们的介晶性质与介晶单元的性质和树突的结构一致。包含两个氰基联苯介晶单元的第一代聚(芳基酯)树状分子被用于功能化金纳米粒子。为了完全覆盖,当金纳米颗粒散布到碳涂覆的铜网格上时,观察到了近乎纳米级的近晶状超分子组织。该结果表明,本文报道的树枝状配体起自组织促进剂的作用。
