Molecular Design of Metal-Ligand Chromophoric Building Blocks and Their Supramolecular Assembly and Functions

Abstract

Recent works in our laboratory have shown that novel photofunctional metal complexes could be assembled through the use of various metal-ligand chromophoric building blocks. In this presentation, various design and synthetic strategies together with the successful isolation of new classes of chromophoric metal complexes will be described. A number of these complexes have been shown to display rich luminescence behavior. Correlations of the luminescence behavior with the electronic and structural effects of the metal complexes have been made. Some of these complexes have also been shown to undergo supramolecular assembly to give a variety of structures and morphologies. The characteristics of these complexes could be fine-tuned for specific applications and functions through rational design and assembly strategies based on various coordination motifs or weak non-covalent metallophilic and π-π interactions.
