An ECNU research team led by Prof. Xu Lin with the School of Chemistry and Molecular Engineering has made a major breakthrough in supramolecular fluorescence regulation.
The researchers used the precise control strategies of photo-induced electron transfer (PET) and intramolecular charge transfer (ICT) to overcome the adverse impact of heavy-metal coordination and assembly on fluorescence quenching. The increase in post-assembly fluorescence quantum efficiency and amplified-wavelength displacement was also studied.
The research breakthrough has been published in the Nature Communications.
This research provides a theoretical basis for the design and construction of hyper fluorescence quantum efficiency and supramolecular fluorescent metal assemblies with wide-range emission. The essay about the finding Switchable organoplatinum metallacycles with high quantum yields and tunable fluorescence wavelengths” has been published in the Nature Communications.
