| 概 要 |
Control over dynamics of charged and excited states of molecules is of fundamental importance for utilization of these states in many applications including those in biomedicine and energy science. The first part of the presentation will focus on the studies that explored magnetic control of molecular emissivity. We demonstrated magnetic modulation of molecular emissivity in solution by incorporation of magnetically susceptible intermediate species, radical pairs or triplet-triplet exciton pair, in the photophysical pathways leading to emissive states. These results set the stage for rational design of optical imaging probes with magnetically controlled emissivity. The second part of the presentation will discuss how small structural changes, such as dihedral angles in conjugated molecules, control the energetics of charged and electronic states, and their implications in polaron and exciton transport. |
