A new type of soluble, solution-processable platinum(II) polyyne polymers based on phenanthrenyl-imidazole chromophore and their corresponding diplatinum model complexes were synthesized via the CuI-catalyzed dehydrohalogenation reaction of the platinum(II) chloride precursor and each of the diethynyl ligands. The photophysical (absorption and emission spectra), thermal, electrochemical and photovoltaic
通过CuI催化氯化铂(II)前体和每个二乙炔配体的脱卤化氢反应,合成了一种新型的可溶解的可溶液加工的基于菲-咪唑发色团的铂(II)多炔聚合物及其相应的二铂模型配合物。 。研究了聚合物的光物理(吸收和发射光谱),热,电化学和光伏性质。两种聚合物均在459-466 nm处显示出强吸收带,并评估了沿聚合物主链添加噻吩环的效果。研究了通过将这些金属聚合物与甲基富勒烯共混制备的块状异质结太阳能电池,尽管聚合物的带隙能不低,但功率转换效率达到了0.39%。
