Molecular design of luminescent metal-based materials

A series of soluble di- and polynuclear transition-metal acetylides with ri ch luminescence behavior have been designed and successfully isolated. The photophysical and photochemical properties have been studied. Luminescent p olynuclear metal complexes have also been obtained based on the metal chalc ogenide building block. These high-nuclearity transition-metal chalcogenide complexes have been structurally characterized and shown to display rich l uminescence behavior. Various approaches and strategies to design and synth esize luminescent polynuclear metal complexes that may find potential appli cations as chemosensors and luminescence signalling devices will also be de scribed.
