Platinum diimine dithiolate

Cummings SD, Eisenberg R. Tuning the excited-state properties of platinum(II) diimine dithiolate complexes. J Am Chem Soc 1996 118 1949-60. 

The long lifetimes of CT excited states of the Pt(diimine)(dithiolate) complexes allow for bimolecular photochemistry, often involving oxidation of the complex. The earliest report of photoreactivity of these complexes dealt with the photooxidation of Pt(bpy)(tdt) (20) following excitation at 577 nm in chloroform (118). The reaction proceeds with a quantum yield of < ) = 0.03 and was attributed to ET to the halocarbon solvent (Eq. 8) similar to the CTTS photooxidation chemistry of the platinum bis(dithiolate) dianions described above. 

Another chapter examines recent work in the area of metal-organic complexes derived from palladium(II) and platinum(II) diimine-dithiolate complexes. Pilato (Qiap. S), who is a leader in the development of new luminescent complexes of this family, has pioneered their application to sensing oiganophosphates and oxygen. His chapter describes the synthesis of these complexes, provides a comprehensive overview of their photophysical properties, and gives some examples of their application to the development of solid-state sensors.
