can afford complementary information is required. We demonstrate in this work that resonance excitation energytransfer phenomena, measured by fluorescence spectroscopy in combination with other optical spectroscopies, can be a valuable tool to obtain supplementary thermodynamic data about complex supramolecular landscapes that other methods fail to provide. In particular, noncovalent macrocyclization

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.
