On June 28, 2025, Prof. Hu Bin from the School of Materials Science and Engineering of South China University of Technology was invited to visit the Institute of New Concept Sensors and Molecular Materials and presented a report titled “Revealing the Deep-level Photoelectronic Behaviors of Excited State Dynamics by Utilizing Optical and Spin Physical Experimental Approaches”.

Hu Bin presented the coupling relationship among “spin-polarization-energy” parameters during the excited state process and introduced the research progress of his team in several frontier systems, including the abnormal electron-phonon coupling effect induced by molecular aggregation, the self-enhanced photovoltaic behavior of photo-induced molecular polarization excitation, the chiral exciton helical order transition, and the abnormal luminescence behavior of spin excitons triggered by charge transfer states. He also highlighted the latest experimental results such as the circularly polarized exciton magnetic response in the report, which expanded the design ideas of new optoelectronic materials.
