Research Topic

Synthesis, Characteristics, and Device Applications of Electronic Polymers

Our research interests are focusing on the following three subjects: (1) investigate the structure-electronic property relationships; e.g., dielectric property, electrochemical property, and band gap; (2) synthesis and mechanism of nanoporous poly(silsesquioxanes) by templating amphiphilic block copolymers; (3) new conjugated polymers: synthesis, theoretical electronic structures, and applications.

Preparation and characterization of optical polymers

Our research interests are focusing on the synthesis and characterization of optical polymer films and polymer waveguides: (1) control of refractive index and its dispersion, near-infrared absorption, and optical loss by molecular tuning; (2) synthesis of optical polymers including multi-component acrylics, organic-inorganic hybrid nanocomposites, and polyimides; (3) fabrication of optical devices and their characteristics: high refractive index films, antireflective films, planar and channel waveguides.
