The present invention provides a modular approach to preparing a large array of substituted cyclometalated compounds which behave as dyes having intense absorbance bands in the visible spectrum The compounds include at least one terpyridine-type ligand (tpy) and one cyclometalated tridentate ligand having the bonding motif N,C,N' or C,N, N'. In particular, compounds of formula (I) and formula (II), as shown, where M and R1 to R4 are as defined herein, are disclosed The utility of these compounds in dye-sensitized solar cells (DSSCs) is also taught.
