Negative solvatochromism of push–pull biphenyl compounds: a theoretical study

, 2015
We have investigated the negative solvatochromism observed for 4-(phenyloxido)-N-methylpyridinium in solvents of varying polarity using a hierarchy of solvation models (continuum, discrete, and mixed) combined with a (TD)DFT description.
