研究领域

Organic Chemistry/Materials/Nanoscience

My research is focused on the interfacial area between organic chemistry and materials science. This area has rich opportunities for organic chemists both in fundamental science and practical technologies. 1. Polymer Chemistry: We are especially interested in exploring reactions that require mild reaction conditions for syntheses of functional polymers and materials. 1.1. Palladium-mediated coupling reactions (The Heck reaction, the Stille coupling reaction)for polycondensation; 1.2. Living ring-opening polymerization for the synthesis of biocompatible polyesters; 1.3. Exploring new polycondensation reactions as an alternative method to the Stille reaction. 1.4. Ladder polymer chemistry. 2. Functional Polymers: 2.1 Solar cell polymers: Our group is engaged in research effort to develop low bandgap polymers that can efficiently harvest and convert solar energy into electricity. Two types of polymers are being designed and synthesized. a. p-Type low bandgap semiconducting polymers. Both Linear and 2 dimensional polymers are pursued. b. n-Type semiconducting polymers as electron-acceptors. This project requires development of synthetic approaches to new monomer and polymer structures. In addition to the synthetic work, extensive research effort is devoted to the elucidation of light conversion mechanism, charge separation dynamics and structure/property relationship. 2.2 Chiral polymers and Helical molecules. This project concerns the effect of chirality of polymers on their properties, such as electron-optic properties and self-assembly. 2.3 Functional polymers containing metal complexes. Metal complexes exhibit rich electro-magnetic and optical properties, which can be explored for electro-optic materials and catalysis. One of our projects is to combine organic conjugated polymers with transition metal complexes to investigate new physical properties, such as photorefractive effects, photoconductivity, light emission and novel redox properties. These polymers exhibit promising potential for applications in solar energy conversion, sensors, polymer-supported electrodes, nonlinear optics, photorefraction and electroluminescence. 2.4 Molecular Electronics. This project explores the power of organic chemistry in designing and synthesizing molecular electronic components, such as molecular diodes, molecular switches and information storage material. A typical example is the synthesis of molecular diodes and demonstration of their rectification effect. The molecular diode consists of conjugated diblock. These materials present the unlimited opportunity to further fundamental knowledge of the electronic and structural properties of organic electroactive materials.
