From August 3 to 6, 2023, Prof. Fang Yu, Prof. Ding Liping, and Prof. Liu Jing participated in and presented at the 18th National Photochemistry Symposium of the Chinese Chemical Society held in Changchun.

Fang Yu's plenary report was titled "Film-based Fluorescent Sensors - From the Innovation of Sensitive Materials to the Development of Hardware Structure", Prof. Ding Liping's invited report was titled "Construction of Interactive Responsive Fluorescent Sensing System and Its Differentiation and Recognition Performance", Prof. Liu Jing's invited report was titled "Excited State Regulation of Assembled Fluorescent Small Molecules and Efficient Sensing of Gas-Phase Pollutants".

With the theme of "Supramolecular Photochemistry", the conference was co-sponsored by the Photochemistry Committee of the Chinese Chemical Society and Jilin University, and organized by the School of Physics of Jilin University, which was attended by more than 600 scholars from more than 120 organizations in China, including eight CAS academicians and more than 40 other national high-level talents.
