Molecular- and nanoparticle-based devices are expected as candidates of active elements in future information science and technology for communication, memory, sensing and display.  Our research interest is focused on new photo-functional molecular and nano-scale materials which actively interact with photons including photo-responsive molecules, polymers and nanoparticles.   As "Photonic Molecular Informatics" in future is expected to be based on functionality of single molecules and single quantum particles, we also aim development of molecules, nanoparticles and detection and manipulation systems toward science and technology of single molecules and single quantum particles.
