A novel tetrathiafulvalene (TTF)-based main-chain polymer (6TTF-polymer) was successfully synthesized via a condensation polymerization between a newly synthesized dihydroxy TTF derivative and a malonyl chloride, and its chemical structure was characterized by spectroscopic techniques. Molecular weight of the 6TTF-polymer (9,030 g/mol by gel permeation chromatography) was large enough to form the ductile film. The electrochemical and optical properties of the 6TTF-polymer were further estimated by cyclic voltammetry, ultraviolet and photoluminescence spectroscopes. The highest occupied molecular orbital level ($E_HOMO}$=-4.79 eV) and band-gap energy ($E_g$=1.91 eV) of the 6TTF-polymer suggested that TTF-based polymer could act as a good electron donating material for the optoelectronic applications.
一种新型的四硫富瓦烯(TTF)基主链聚合物(6TTF-聚合物)通过新合成的二羟基TTF衍生物与马隆酰氯之间的缩合聚合成功合成,其化学结构通过光谱技术进行了表征。6TTF-聚合物的分子量(通过凝胶渗透色谱法测得为9,030 g/mol)足够大,可以形成可挠性的薄膜。通过循环伏安法、紫外光和光致发光光谱仪进一步估算了6TTF-聚合物的电化学和光学特性。6TTF-聚合物的最高占据分子轨道能级($E_HOMO}$=-4.79 eV)和带隙能量($E_g$=1.91 eV)表明,TTF基聚合物可以作为良好的电子供给材料用于光电应用。
