A series of carbazole-based D-A copolymers were synthesized to investigate the influences of conjugation length and structural distortion on intramolecular charge transfer (CT) complexation between the donor (D) and acceptor (A) components. The copolymers were comprehensively characterized using TGA, DSC, UV-vis, and photoluminescence spectroscopy, cyclic voltammetry, and DFT calculations. P(3,6C-DTBT), which was linked by a thienyl-benzothiadiazole (DTBT) group at the 3,6-positions of the carbazoles so as to directly involve the electron-rich nitrogen atoms in conjugation, exhibited conjugation breaks in the middle of the carbazole units. In this talk, I will address the effects of intra- and inter-molecular doping into such photoactive condcuting polymers on hole mobility, nanostructures, and photovoltaic performances. |
