Blue-shifted aggregation-induced enhancement of a Sn(iv) fluoride complex: the role of fluorine in luminescence enhancement†
Abstract
A new type of blue-shifted aggregation-induced emission enhancement was observed for a Sn(IV) fluoride complex, resulting in strong emission in the solid state as compared with that in solutions. The fluorinated Sn(IV) complex has a significantly more intense emission efficiency compared to the chlorinated Sn(IV) complex, which is attributed to stronger σ bonding.
