Abstract Two new cyclometalated ruthenium sensitizers NC102 (1) and NC103 (2), where the two NCS-ligands of the N3 analog were replaced with the 2-thiophen-2-yl-pyridine and 2- benzo [b] thiophen-2-yl-pyridine ligands, respectively, were designed and synthesized for dye-sensitized solar cell applications. The effects of these two ligands on the photophysical behavior of ruthenium complexes were investigated by their optical, electrochemical, and ...
