Driving the Emission Towards Blue by Controlling the HOMO‐LUMO Energy Gap in BF 2 ‐Functionalized 2‐(Imidazo[1,5‐ a ]pyridin‐3‐yl)phenols

Several boron compounds with 2-(imidazo[1,5-a]pyridin-3-yl)phenols, differentiated by the nature of the substituent (R) in the para position of the hydroxy group, have been synthesized and thoroughly characterized both in solution (
