Synthesis and photophysical properties of tripod BODIPY dyes bearing mono-phenolic derivatives

A series of new tripod boron dipyrromethene (BODIPY) dyes bearing mono-phenolic derivatives were synthesized and characterized. An optimized reaction condition for the synthesis of the bis-substituted intermediates was obtained. An unanticipated phenol-dependent effect on the yields was found and a hypothetic mechanism was proposed to elucidate the reactivity of the tripod dipyrromethene species during the complexation step. The new dyes showed typical photophysical properties of the BODIPY fluorophore.
