研究领域

The major focus of our research is on the molecular design and synthesis of novel inorganic/organometallic metal complexes that may find potential applications as functional metal-based molecular materials. Of particular interest are luminescent polynuclear metal complexes that show weak metal-metal interactions and luminescent metal complex and supramolecular systems of charge-transfer excited states, with d6, d8 or d10 metal centres, in particular those containing alkynyl, chalcogenido, chalcogenolato, pnictogenido and polypyridyl ligands. Through the systematic study of the electronic spectroscopy of the newly synthesized metal complex systems, a fundamental understanding of the spectroscopic and luminescence origin as well as the structure-property relationship of these complexes could be established. Apart from their fundamental spectroscopic, mechanistic, electrochemical, photoluminescence (PL), and photochemical studies, attempts will be made to explore their potential applications as functional molecular materials in the following areas: Optoelectronic Materials Spectrochemical and Luminescence Chemosensors and Biolabels Photochromic and Photoswitching Materials Supramolecular Assemblies and Organogels Molecular Electronics and Resistive Memories Nanoclusters and Nanomaterials
