Regioregular organometallic polymers with titanacyclopentadiene units, obtained from terminal diynes and a low-valent titanium complex, were subjected to reactions with disulfur dichloride and selenium (I) chloride to give π-conjugated polymers with thiophene and selenophene units in the main chain in 63% and 86% yields. Their number-average molecular weights were estimated as 4300 and 5700, respectively. Both polymers were found to be fully π-conjugated and their HOMO energy levels were remarkably high (-5.3 eV and -5.0 eV for thiophene- and selenophene-containing polymers, respectively) as supported by their UV-vis absorption spectra and CV analyses.
具有钛杂环戊二烯单元的区域规整的有机金属聚合物，由末端二炔和低价钛配合物制得，与二硫化二氯和硒（I）氯化物反应，以 63%和 86%的产率得到具有噻吩和硒吩单元的主链的π-共轭聚合物。它们的数均分子量分别估计为 4300 和 5700。通过它们的紫外-可见吸收光谱和 CV 分析，发现这两种聚合物都是完全的π-共轭的，并且它们的 HOMO 能级非常高（分别为-5.3 eV 和-5.0 eV，对于含噻吩和硒吩的聚合物）。
