"Polymer & Light" is the keywords of our study. Welcome to the home page of our "Polymer Structure and Function" research group. The focus of our group is to design and develop novel photo/electronic functionality of polymeric materials through fabrication of well-defined structures of polymer assemblies. Current interests include characterization of nano-structures by means of near-field optical microscopy and fluorescence spectroscopy. Based on fundamental knowledge of photophysics and photochemistry, we investigate polymer structure and dynamics from a view of polymer science. In addition, our group has a fully equipped laboratory, including a variety of laser systems, spectrometers, optical and scanning probe microscopes, surface analysis instruments, and a complete wet laboratory for preparation and characterization of samples. You can see the photos of our facilities from this page. 1. Structure and Dynamics of Polymers Investigated

2. Photochemistry and Photophysics in Polymer Systems
and Development of Novel Optoelectronic Devices and Organic Solar Cells
We study photochemical and photophysical processes in polymer systems such as excitation energy transfer and electron transfer by using ultrashort pulsed laser systems and time-resolving spectroscopy. We also aim to develop novel optoelectronic devices in which fundamental processes are well controlled by nanostructured ultrathin polymer films. In particular, our recent research focuses on design of polymer solar cells based on novel idea and concept in polymer structure and functions.
