The present invention provides substituted cyclometalated dyes with wider absorbance bands in the visible spectrum. The compounds have hexacoordinate structures as shown in formula (I) where the central transition metal (M) is bonded to two substituted bipyridine ligands and a cyclometallated 2-phenylpyridine ligand. The R groups are as defined herein. Also provided are a method of manufacturing the dyes and the use of same in electric and photoelectric devices such as dye-sensitized solar cells (DSSC), organic light-emitting diodes (OLED), field effect transistors (FET) and photoelectrochemical (PEC) cells.
