Synthesis and photophysical properties of tripod BODIPY dyes bearing mono-phenolic derivatives
摘要:
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. (C) 2014 Elsevier Ltd. All rights reserved.

The invention relates to a photopolymer formulation comprising polyurethane matrix polymers, writing monomers, and photoinitiators, wherein the writing monomers comprise compounds of formula (I), where R1, R2, R3 independent of each other are each a halogen atom or an organic radical, wherein at least one of the radicals is an organic radical comprising a radiation hardening group. The invention further relates to the use of the photopolymer formulation for producing holographic media.
