在此，我们报告了一种结合超分子化学和 LB 技术来调节 PDA 薄膜手性的新模型。 PCDA 分子的螺旋堆积和所得 PDA LB 薄膜的手性光学性质可以通过不同的偶氮苯衍生物轻松调节。此外，还详细研究了偶氮苯发色团的光异构化对 PCDA 组装体螺旋形成的影响。
Herein, we report a novel model that combines supramolecular chemistry and the LB technique for the chirality regulation of the PDA films. The helical packing of PCDA molecules and the chiroptical properties of the resulting PDA LB films can be easily modulated by different azobenzene derivatives. Moreover, the effect of the photo-isomerization of azobenzene chromophores on the helical formation of PCDA assemblies is investigated in detail.
