The spectroscopic and electrochemical studies suggest the energy structure of this class complex can be easily controlled by modification. With the introduction of electron-donating arylamino groups, the obtained complexes show intense and continuous absorption bands in the region of 250-550nm with strong metal-to-ligand charge transfer dπ(Pt →π* transitions (ε~ 2×104 dm3 · mol-1 · cm-1). Complexes involving the construction of D-π-A type systems also display continuous absorption bands in the region of 400-750nm, rising from the overlapping effect of MLCT and LL'CT bands.
