| Research Abstract |
In this research project, we have demonstrated syntheses of new photochromic molecules, based on the unprecedented novel idea and molecular design, with an objective for developments of molecular photo-nanotechnology. We have synthesized nanoscale photochromic rings, which can change their molecular conformations in response to the light, through attachments of azobenzene components into cyclic oligopyrroles. We have successfully isolated the cyclic oligopyrroles, and found that the macrocycle, composed of one azobenzene and four pyrrole units, shows the photoisomerization with higher efficiency.
