Molecular triplet emitters - from design to assembly and functions

In this presentation, various design and synthetic strategies together with the successful isolation of a series of complexes of selected metals are described. A number of these complexes have been structurally characterized 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 and functions as triplet light-emitters and functional materials.
