Facile and environmentally friendly halogenation of BODIPYs in deep eutectic solvent
摘要:
A deep eutectic solvent based on choline chloride and 1,1,1,3,3,3-hexafluoro-2-propanol was prepared. This deep eutectic solvent was used as the reaction medium for halogenation of boron dipyrromethene in the presence of N-halosuccinimide, which delivered the corresponding products in good to excellent yields (79-94%) in short reaction time (usually within 30 min). Moreover, this deep eutectic solvent could be easily prepared, recovered and reused for several runs without significant loss in the yields. (C) 2014 Elsevier Ltd. All rights reserved.

understanding of how the chemical structure of a chromophore influences its photophysical properties. We here describe the synthesis of a library of BODIPY dyes, exploring diversity at various positions around the BODIPY core. The results show that the nature and position of substituents have a dramatic effect on the spectroscopic properties. Substituting in a heavyatom or adjusting the size and orientation
