Expertise

Organic and Polymer Synthesis, Nanomaterials Synthesis, Green Chemistry, Ionic Liquids, Anticancer Drugs

Additional Information

My interests focus on organic and polymer synthesis in general. More specifically, we are interested in developing novel light-emitting and liquid-crystalline polymers for their multitude applications in modern technology, including biosensors. In another project, we are developing ionic liquids based on the concept of green chemistry, and liquid-crystalline and light-emitting organic salts to make them functional materials. Carbon nanotube-based composite materials based on ionic polymers are of significant interest in our group. In recent years, we are also actively pursuing the development of cisplatin analogs for the development cancer therapy.

Liquid-Crystalline Polymers

His principal research projects are in the broad field of liquid-crystalline polymers that typically include thermotropic liquid-crystalline polyesters, thermotropic and lyotropic liquid-crystalline ionic polymers (viologen polymers); thermotropic liquid-crystalline hydrogen bonded materials via supramolecular chemistry, and liquid-crystalline dendritic macromolecules and polyrotaxanes.

Light-Emitting Polymers

Recently, he is actively involved in the design and synthesis of poly(arylated-pyridinium salts) with organic counterions that exhibit both lyotropic liquid-crystalline and light-emitting properties. These polymers are targeted for the development of blue-light emitting polymers with the structural variations of both arylated-pyridinium moieties and organic counterions. They are of significant interest for combining light emitting properties with the self-organization of liquid-crystalline properties to produce linearly polarized electroluminescence. Since they are cationic polyelectrolytes, they can be useful partners for the build up of multilayer assemblies with anionic polyelectrolytes by the well-known sequential deposition technique to create a novel class of materials having specific functional properties-smart materials. All of these projects are the integral components for the development of materials science and engineering program.

Green Chemistry

In another project, he is developing room-temperature liquid-crystalline ionic salts that have great potential as organized reaction media for clean organic synthesis. It is targeted to develop green chemistry to strengthen the environmental chemistry program. Microwave chemistry both in organic synthesis as well as polymer synthesis is also an integral component for the development of green chemistry program.
