On May 9, 2023, Prof. Lu Wei from the Department of Chemistry of Southern University of Science and Technology (SUST) was invited by the Photonic Nose and Molecular Materials Group to give a report to the group members in the 1668 Lecture Hall of Zhi Zhi Building, Chang’an Campus. The report was hosted by Prof. Liu Jing and the group teachers and students attended the presentation.

In the report titled Photoactivated Phosphorescence (PAP): Photochemical Deoxidation and Visualisation Applications, Lu Wei presented his group’s research findings that long-lived phosphorescence of organometallic complexes can be reversibly activated by controlled light exposure in solutions of photochemical deoxidising solvents, which are sacrificial solvents that release the photooxidation tension in solution and protect the long-lived triplet excited state, and demonstrate that PAP is a general property of organometallic complexes with long-lived triplet excited states. After elucidating the PAP mechanism, his group is also implementing several technical applications of PAP.

After the report, Lu Wei discussed related issues with the teachers and students present.
