Recently, Prof. Xu Lin from the School of Chemistry and Molecular Engineering and the research team headed by Sun Haitao from the State Key Laboratory of Precision Spectroscopy of ECNU have made important progress in the field of supramolecular chemistry. Their research results titled “Rotaxane-Branched Dendrimers with Enhanced Photosensitization” were published in the Journal of theAmerican Chemical Society, a top journal in chemistry(J. Am. Chem. Soc., 2020, 10.1021/jacs.0c07292).
On the basis of previous studies, the researchers carried out interdisciplinary cooperation, giving full play to their respective advantages in the construction of a supramolecular optical system and quantum theoretical calculations to explore a reasonable and ingenious molecular design for the photosensitization mechanism of photosensitizers. Based on a simple yet efficient synthesis method, multiple heavy atomic platinum and photosensitizer moieties were successfully incorporated on the axles and wheels of the rotaxane units, and the third-generation rotaxane-branched dendrimer was synthesized through a controllable divergent approach.
Li Jianwei, a PhD candidate from the School of Chemistry and Molecular Engineering of ECNU, is the first author of this paper and the corresponding authors are Prof. Xu Lin and researcher Sun Haitao. This project gained support from the Outstanding Youth Science Foundation of the National Natural Science Foundation of China, Pujiang Talent Program of Shanghai, the Innovation Program of Shanghai Municipal Education Commission, etc.
Prof. Xu Lin, as a crucial researcher in the supramolecular chemistry group led by Prof. Yang Haibo from ECNU, has long focused on researching supramolecular fluorescent chemistry. Prof. Sun Haitao, a key member of the femtosecond spectral imaging and light field regulation team led by Prof. Sun Zhenrong from ECNU, is mainly engaged in quantum chemical theoretical calculation research.
