合成了两个新的全氟苯基桥联双（二噻吩并[3，2-B：2 '，3'-d]磷杂环戊烯）配合物，并通过静态/动态荧光光谱、循环伏安法（CV）和密度泛函理论（DFT）研究了它们的电子物理和氧化还原性质.化学物理研究揭示了一个有趣的分子内电荷转移（ICT）发生在极性溶剂中的两个相同的二噻吩磷杂环戊烯部分之间的理论研究所支持的。CV实验表明，双磷杂环戊二烯物种具有较小的电荷转移（CT）的能隙比相应的单一二噻吩磷杂环戊二烯物种。
Two new perfluorophenylene-bridged bis(dithieno[3,2-b:2',3'-d]phosphole)s have been synthesized and their photophysical and redox properties have been investigated via static/dynamic fluorescence spectroscopies, cyclic voltammetry (CV), and DFT calculations. The photophysical studies revealed an interesting intramolecular charge transfer (ICT) occurring between the two identical dithienophosphole moieties in polar solvents that was supported by the theoretical studies. The CV experiments show that the bisphosphole species exhibits a smaller charge transfer (CT) energy gap than the corresponding single dithienophosphole species.
