The ortho- and para-amino groups allow the phenyl group to inductively release greater electron density into the dipyrromethenes resulting in relatively strong intermolecular hydrogen-bonding with the terminal BF2 groups, whereas the meta-analog formed weaker hydrogen-bonds. The intensities of the H-1 NMR peaks in concentrated solutions all increased with F-decoupling. (C) 2008 Elsevier Ltd.
