A multi-chromic boron trifluoride-pyridyl Lewis adduct

Chem Commun (Camb). 2024 Mar 12;60(22):3051-3054. doi: 10.1039/d3cc05996k.


A boron trifluoride-pyridyl Lewis adduct is reported, which exhibits various types of chromism and high solid-state photoluminescence quantum yields, as well as excitation-dependent emission in the mechanically ground form. The facile synthetic approach offers a simple and potentially versatile strategy for inducing chromism in pyridyl ligands with donor moieties. We envisage this approach as having a dual benefit: simplicity and extensive applicability.
