Using conformatcnally constrained bi- and ter-thiophenes, the effects of inter-ring torsional angles on spectroscopic properties of the corresponding polymers are demonstrated; effects on conductivity are complicated by inter-chain contributions.

Abstract A convenient synthesis of a number of 3,3′-bridged-bis-2,2′-thienyls as potential building blocks for novel conducting polymers is reported. The UV-spectra and oxidation potentials of these novel compounds are given. Although the UV-spectra correlated to the degree of coplanarity of these species, the oxidation potentials did not correlate, and no tendency to polymerize was observed for the
摘要报道了许多 3,3'-桥连双 2,2'-噻吩基的方便合成,作为新型导电聚合物的潜在构建单元。给出了这些新化合物的紫外光谱和氧化电位。尽管紫外光谱与这些物质的共面度相关,但氧化电位不相关,并且没有观察到 N-桥连噻吩基 1a-1d、2a-2c 的聚合趋势。这种行为与其他 2,2'-二噻吩基的结果。这些发现可以通过在电子转移之前电极表面上 N 桥联二噻吩基分子的氮和硫吸附取向来解释
