Planarisation or a twist? Using steric engineering to unlock the origin of mechanofluorochromic red-shifts

Year: 2025

Type: article

Abstract: -diphenylamino donor and pyridinium acceptor induces a notable red-shift in emission maximum, with the mechanofluorochromic response also correlated with the same process. This research aims to address the oft-invoked explanation that planarisation induces red-shifted emission, highlighting that this effect is not universal and that systematic studies are essential. Further, this elegant steric engineering approach may be applied to other mechanochromic systems to determine the nature of their geometry changes.
