Molecular Design of Luminescent Metal-Based Materials

Polynuclear transition metal complexes have been shown to exhibit rich luminescence behavior. The recent reports on the potential applications of alkynyl metal complexes as nonlinear optical materials, molecular wires and rigid-rod materials, and the wide variety of possible bonding modes of the alkynyl moiety have aroused our interest in investigating their potential in the design and synthesis of di- and polynuclear metal complexes. In this presentation, the design and successful isolation of a series of soluble di- and polynuclear transition metal acetylides with rich luminescence behavior will be described11,21.
