Research Outline

Chemiluminescence (CL) is a phenomenon in which excited molecules are generated by thermochemical reactions to emit light. It would be possible to detect extremely minute structural changes in a soft crystal at the atomic and molecular levels as CL changes, since ultrahigh sensitivity analysis is made possible by observing CL as a probe. In this research, we will create soft crystal CL systems that initiate luminescence by external stimulations to crystals. By elucidating the mechanism of stimulus-responsive CL with thermodynamic, kinetic, and quantum theoretical approaches, we also aim for spatiotemporal control of CL produced at arbitrary position and time in soft crystals. Specifically, we will conduct our research in the following two ways, (1) organic peroxides and luminescent redox-active metal complexes will be prepared for CL in soft crystals to establish the requirements for CL-active crystal structures and elucidate the CL reaction mechanisms; (2) We will take advantage of recently-developed ultra-high-resolution microscopy and time-resolved spectroscopy based on full-time “in-situ” observations of stimulus CL responses.
