PHOTOSYNERGETICS

The purpose of the present project is to develop and advance excitation methods and molecules/molecular assemblies that can overcome these three restrictions, by exploring methods beyond the conventional paradigm, "one-photon and one-molecule outcomes"; such as multiple excitation, multiphoton absorption, strong modulation of electronic states, coherent and cooperative responses of molecules, and rational design of molecular assemblies. By integrating these investigations, we aim to acquire general principles on "photosynergetics" enabling more effective utilization of the light energy in molecular systems.
