In our research group, we are focusing on our activities to the design and study of several research categories of "Organic Materials and Functional Colorant Materials". At this time, "Organic Chemistry Materials" covering with functional materials synthesis, photo-induced switching materials, absorption/emission materials, chemosensor materials, optoelectronics materials, luminescence materials, DSSC (dye-sensitized solar cell) dye materials and functional D-p-A system have been research-focused and the related works have been carried out.
