1,8-Naphthalimide-based highly blue-emissive fluorophore induced by a bromine atom: reversible thermochromism and vapochromism characteristics†
Abstract
We report a structurally simple 1,8-naphthalimide-based fluorescent molecule. Its solid shows an intense blue emission with an absolute fluorescence quantum yield of up to 82.33%. The novel luminogen exhibits reversible thermochromism and vapochromism behaviors.
