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.

The response of the metal-to-ligandcharge-transfer (MLCT) band to variability in terminal substituents within a related set of tridentate polypyridyl and cyclometalated Ru(II) complexes is reported. These complexes are formulated as [Ru(tpy-R1)(tpy-R2)](PF6)2 (1−6; tpy = 2,2′:6′,2′′-terpyridine; R1 = −H, −2-furyl, or −OMe; R2 = −H, −2-furyl, or −CO2H) and [Ru(tpy-R2)(dpb-R1)]PF6 (7−10; Hdpb = 1,3

crossing the spectrum of visible light. Most of the Pt complexes are strongly luminescent (Φ = 0.32−0.63) and have short luminescence lifetimes (τ = 4−7 μs) at room temperature. The lowest excited state of the Pt(N∧C∧N)X complexes is identified as a dominant ligand-centered 3π−π* state with some 1MLCT/3MLCT character, which appears to have a larger 1MLCT component than their bidentate and tridentate analogs
