Abstract

Ultraviolet absorption and Circular Dichroism spectra in the region 300-700 nm for highly regioregular samples of Poly[3[(S)-2-methylbutyl]-thiophene] are reported for solutions in good and poor solvents, at variable temperature, and for films in various conditions. In the latter case novel CD data up to the melting temperature provide some hints for the self-assembling process towards supramolecular organization. UV-visible and CD data are also reported on the related polymer Poly[3,4-di[(S)-2-methylbutyl]-thiophene].

区域规则聚[3 [(S)-2-甲基丁基]-噻吩]和聚[3,4-二[(S)-2-甲基丁基]-噻吩]的圆二色光谱。
本文报道了高度区域规则的聚[3[(S)-2-甲基丁基]-噻吩]样品在300-700 nm区域的紫外吸收和圆二色光谱,分别适用于好溶剂和差溶剂、不同温度和不同条件下的薄膜。在后一种情况下,新的CD数据直到熔化温度为自组装过程向超分子组织提供了一些线索。相关聚合物聚[3,4-二[(S)-2-甲基丁基]-噻吩]的紫外可见和CD数据也有报道。
