Luminescent metal-based materials - Their design and assembly from a molecular perspective

Abstract

Recent work in our laboratory has shown that novel luminescent homo- and hetero-metallic metal-based molecular materials could be assembled through the use of various building blocks such as chalcogenides, pnictogenides and alkynyls. A number of these complexes have been structurally characterised and shown to display rich luminescence behaviour. The luminescence properties have been studied and their emissive origins elucidated. Correlations of the luminescence behaviour with the electronic and structural effects of the ligands and metal complexes have been made. Different approaches and assembly motifs have been employed to tune the absorption and emission characteristics of these materials based on an understanding of their spectroscopic origins. Through rational design and assembly strategies, these molecular materials may find potential applications in materials science and sensor technology. © 2005 Académie des sciences.
