Diagonal and Vertical B ← N Lewis Pair Functionalized Perylenes
Yufeng Zhang, Zhenyi Zhang, Lei Ji, Wei Huang
Abstract
Two novel multiple B ← N Lewis pair functionalized perylenes are reported. While OBN-Pery shows a centrosymmetric and planar architecture, PBN-Pery displays an axisymmetric and twist structure. B ← N functionalization in both of them results in a large decrease in the HOMO–LUMO energy gap. PBN-Pery in particular has a low LUMO energy level (−3.00 eV) and red emission at the NIR I region with high fluorescence quantum yield.
