Low-lying triplet metal-to-ligand charge transfer (3MLCT) transitions of osmium complexes induced by spin-orbit coupling (SOC) are promising for extending the photocurrent response in dye-sensitized solar cells. In this study, a new osmium complex (CYC-33O) is presented, incorporating a 2-thiohexyl-3,4-ethylenedioxythiophene functionalized bipyridyl ancillary ligand to red-shift the absorption and enhance the absorbance of singlet and triplet metal-to-ligand charge transfer (1MLCT and 3MLCT) transitions. Time-dependent d. functional theory (TDDFT) calculations show that the reinforced 1MLCT and 3MLCT transitions of CYC-33O are mainly from osmium to the 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine anchoring ligand, increasing the heterogeneous electron transfer between CYC-33O and TiO2. The device sensitized with CYC-33O exhibits panchromatic conversion beyond 1000 nm, yielding a photocurrent d. of 19.38 mA cm-2, which is much higher than those of the cells based on the ruthenium analog (CYC-33R) and model osmium complex (Os-3) sensitizers. In the part of experimental materials, we found many familiar compounds, such as 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6COA of Formula: C12H12N2)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.COA of Formula: C12H12N2 Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.
