Perfluorophenylene-bridged bisphospholes: synthesis and unexpected photophysical properties

Author affiliations

Abstract

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.
