Two solution-processable metallopolyynes of platinum functionalized with the electron-deficient 4H-cyclopenta[2,1-b:3,4-b']dithiophen-4-one spacer and their model molecular complexes were synthesized and developed for the applications of polymer solar cells. These metallated polymers possess extremely low bandgaps of 1.44-1.53 eV which extend toward the near-infrared (NIR) range of the solar spectrum, and represent the lowest optical bandgap yet reported for platinum(II) metallopolyynes to date. The structural flexibility, processibility, and good photovoltaic performance make cyclopentadithiophenone-containing polymers prominent candidates for NIR photovoltaic applications.
合成并开发了两种用缺电子的4H-环戊并[2,1-b:3,4-b']二噻吩-4-酮间隔基官能化的铂的可溶液加工金属聚炔及其模型分子配合物，用于聚合物太阳能电池应用。这些金属化聚合物具有1.44-1.53 eV的极低带隙，延伸至太阳光谱的近红外（NIR）范围，是迄今为止报道的铂（II）金属聚炔中最低的光学带隙。结构灵活性、可加工性和良好的光伏性能使含环戊二噻吩酮的聚合物成为近红外光伏应用的突出候选材料。
