Since the end of 2002, a significant focus of our "basic" research program involves the investigation of supra-nanosecond and ultrafast photophysical processes in platinum(II) polyimine chromophores bearing a variety of carbon-based ligands. These strongly-coupled metal-organic systems are of fundamental interest and may serve in a variety of applications including optical power limiting, solar energy conversion, and photocatalysis. In 2005, we started to explore the solid-state vapochromism inherent in some of the platinum(II) MLCT complexes described above. This year we also established a new program in solar energy conversion, focusing largely on the design and synthesis of new Ru(II) inorganic chromophores for dye sensitized solar cells.
