Abstract: A series of soluble di- and polynuclear transition-metal
acetylides with rich luminescence behavior have been designed and successfully
isolated. The photophysical and photochemical properties have been studied.
Luminescent polynuclear metal complexes have also been obtained based
on the metal chalcogenide building block. These high-nuclearity transition-metal
chalcogenide complexes have been structurally characterized and shown
to display rich luminescence behavior. Various approaches and strategies
to design and synthesize luminescent polynuclear metal complexes that
may find potential applications as chemosensors and luminescence signalling
devices will also be described.
