focused on the structure–property relationships of the unique three‐dimensional architecture of the monomer. We have synthesized nine self‐threading bithiophene monomers that have cyclic side‐chains of different size and flexibility: i.e., 21‐, 22‐, 23‐, 24‐, 26‐, and 30‐membered rings composed of paraffinic, olefinic, or alkynic chains. To investigate their structure–property relationships, 1H NMR spectroscopy
最近,我们报道了一种自穿线的聚噻吩作为绝缘分子线的新家族。在这里,我们集中于单体独特的三维结构的结构-性质关系。我们合成了九种具有不同大小和柔韧性的环状侧链的自穿环联噻吩单体:即,由链烷烃,烯烃或环烷烃组成的21元,22元,23元,24元,26元和30元环炔链。要研究其结构与财产的关系,1进行1 H NMR光谱,UV吸收和荧光光谱测量。我们发现环状侧链定义了联噻吩骨架的二面角的可移动范围,从而影响了其光物理性质。因此,如本文所述设计具有原子精度的结构的能力将导致对绝缘分子线的电子特性的微调。
