Tetradentate carbene–anilido boron complexes: highly fluorescent dyes with larger Stokes shifts than BODIPY analogues†
Abstract
A new class of carbene–anilido boron complexes have been designed and synthesized. The complexes show intense fluorescence with large Stokes shift because of their charge-transfer excited states, different from typical BODIPY dyes. By using a chiral 1,1′-bi(2-naphthol) ligand, dyes exhibiting circularly polarized luminescence can also be facilely developed.
