Abstract

Two random (Zn II-based P1-P2) and two alternating (Ru II-based P3-P4) metallo-copolymers containing bis-terpyridyl ligands with various central donor (i.e., fluorene or carbazole) and acceptor (i.e., benzothiadiazole) moieties were synthesized. The effects of electron donor-acceptor interactions with metal (Zn II and Ru II) ions on their thermal, optical, and electrochemical properties were investigated. Because of the strong ICT transitions between donor and acceptor ligands in both Zn II- and Ru II-based metallo-coplymers and MLCT transitions in Ru II-based metallo-coplymers, the absorption spectra covered a broad range of 260-750 nm with the band gaps of 1.57-1.77 eV. In addition, the introduction of Ru II-based metallo-coplymer P4 mixed with PC 60BM as an active layer of the BHJ solar cell device exhibited the highest PCE value up to 0.90%.
