Borondipyrromethene Dyes with Pentane-2,4-dione Anchors

New, acetylacetone-linked borondipyrromethene (BODIPY) dyes were readily obtained from BODIPY cores by various protocols involving direct grafting with acetylacetone or cross-coupling from a preorganized phenylacacH derivative bearing either an lodo or an ethynyl function. Facile anchoring on TiO2 powder is obtained and scrutinized by FT-IR spectroscopy.
