"Dithiolene metal complexes have a history going back to the 1960's (at least). But, interest in such compounds faded by the seventies. However, there has been a major resurgence, just in the last very few years, and a number of research groups have found exciting new properties (i.e., photochemistry, luminescence), applications as sensors and new materials of industrial interest.
Moreover, very recent (in the last five years, or less) biochemical insights have revealed that dithiolene-metal complexes exist in nature, in certain enzyme active sites. Thus, a segment of the biochemical and (bio)inorganic chem istry community is currently devoting considerable attention to inorganic synthetic, theoretical and other aspects of dithiolene coordination chemistry."
