| Description |
Research conducted in the area of design and self-assembly of self-assembled supramolecular structures has made much progress over the last three decades. In this broad area of research, construction of self-assembled metallasupramolecular structures based on transition metal-ligand interactions (coordination-driven self-assembly) has attracted considerable attention because of their potential applications as sensors, probes, photonic devices, catalysts and in basic host guest chemistry. We plan to use coordination driven self-assembly and supramolecular chemistry in new, innovative directions that mimic the complex recognition, regulatory, multivalency, cooperativity and other properties of biological systems, by incorporating functional units, into these supramolecular structures and control their relative arrangements with respect to each other. This dissertation presents a new approach in the synthesis of multifunctional supramolecules. Based on this approach, a variety of novel molecular polygons and polyhedra with tremendous variations in shape, size and properties has been designed and synthesized. The ultimate goal of this research is the rapid assembly of nanoscale molecular devices for practical applications such as information storage, artificial receptors and drug-delivery agent. Short-termuses include chiral molecular recognition, applications in host-guest chemistry, and catalysis. These multifunctional supramolecular Pt(II)-based ensembles were also synthesized in high yields (90-95%). The macrocycleswere characterized by multinuclearNMRand ESI mass spectrometry. |
