资源简介：
Herein, we report two peri-regioisomers of B←N Lewis pair-functionalized perylenes: the centrosymmetric PBNPf1 and the mirror-symmetric PBNPf2. Mirror-symmetric functionalization more effectively tunes the photoelectronic properties. The LUMO energy levels of PBNPf1 and PBNPf2 are stabilized to −3.00 eV and −3.30 eV. Additionally, the emission maxima of PBNPf1 and PBNPf2 are shifted to 574 and 628 nm, with fluorescence quantum yields of up to 96% and 87%, respectively.
