BINOL blocks as accessible triplet state modulators in BODIPY dyes

Abstract

BINOL moieties of different electronic demand are useful blocks for enabling the photo-production and modulation of triplet excited states in readily-accesible BINOL-based <i>O</i>-BODIPY dyes from standard <i>F</i>-BODIPY precursors. The rapid and rational development of smarter triplet-enabling BODIPY dyes on the basis of this strategy (<i>e.g.</i>, TADF biomarker 4a or room temperature phosphor 4g) paves the way for advancing photonic applications based on organic triplet photosensitizers.
