1 To design and synthesize various functionalized multidentate bridging ligands such as di-, tri- or multi-phosphines or heteroatoms, especially those bearing solubilizing groups and various reactive groups and functional groups, and metal complex precursors, metal nanoparticles, and metal complexes and clusters, 2 To explore the reactivity of the target metal complexes and clusters, and to employ the reaction-based approach to perform post-synthetic modifications to design and synthesize novel metal complexes and clusters, 3 To perform spectroscopic, physical and structural characterization of the newly synthesized functionalized ligands, metal complex precursors and target pre- and post-synthetic modified metal complexes and clusters, 4 To explore the utilization of the reaction-based approach for the post-synthetic modification and construction of clusters-of-clusters and to extend the work to assemble higher-ordered metal cluster networks, assemblies, oligomers and inorganic-organic hybrids, 5 To study the electronic absorption, luminescence and various functional and morphological properties of the metal complexes and clusters, and to study the corresponding changes in the spectroscopic and functional properties as well as morphologies of the clusters-of-clusters, higher-ordered metal cluster networks, assemblies, oligomers and inorganic-organic hybrids, 6 To study the reaction mechanisms and growth dynamics, and the inter-cluster interactions and reaction-based oligomerization behaviour in solution, and 7 To understand and correlate the spectroscopic, electronic absorption, luminescence and functional and morphological properties as well as the underlying factors that lead to the control of their assembly and oligomerization processes.
