摘要

A diboron compound with both 3-coordinate boron and 4-coordinate boron centers,(5- BMes2-2-ph-py) BMes2 (1) and its monoboron analogue,(2-ph-py) BMes2 (2) have been synthesized. Both compounds are luminescent but have a high sensitivity toward light. UV and ambient light cause both compounds to isomerize to 1a and 2a, respectively, via the formation of a C− C bond between a mesityl and the phenyl group, accompanied by a ...
