A General Descriptor ΔE Enables the Quantitative Development of Luminescent Materials Based on Photoinduced Electron Transfer

Weijie Chi, +13 more
- 17 Mar 2020 - 
TL;DR: This work developed a general descriptor (ΔE) for predicting the quantum yield of PET probes, with a threshold value of ~0.6 eV, that is applicable to a wide range of fluorophores, such as BODIPY, fluorescein, rhodamine, and Si-Rhodamine.
