On Mar. 7th, Prof. Qingzheng Yang from Beijing Normal University visited the CCME at PKU for academic report. During his visit, he was guided by Prof. Zhang to tour our lab and exhibition boards, and he also took group photos with us. His primary research focuses on supramolecular photochemistry, with a long-standing commitment to designing and synthesizing novel small-molecule dyes or constructing light-responsive assembly systems. He conducts in-depth studies on the photophysical and photochemical properties of these systems, exploring their applications in luminescent materials, biological probes, photodynamic therapy, and other related fields. We sincerely thank Prof. Yang for his visit!
