Troger’s Base Derived Butterfly Shaped Contorted AIEgens for Dead Bacterial Cell-Imaging

摘要

This work describes the design and synthesis of contorted dual emissive luminogen based on Tr?ger’s base scaffold. The underlying principle of our design strategy was to use Tr?ger’s base as the core scaffold and functionalize appropriately to avoid the detrimental π-π stacking responsible for the emission quenching and induce RIR in the aggregated state and there- after investigate their photophysical, electrochemical, and thermal properties. The unique white light emission of the fluorophores in the solid-state together with excellent bio- compatibility, photo, and thermal stabilities provided an opportunity for the application of one of the molecules for bacterial cell imaging. The luminogen was biocompatible and surprisingly possess an ability to selectively stain the dead bacterial cell debris, a unique property that can be exploited for the confirmation of cell lysis.
