Abstract

Abstract: We report a general design strategy for a new class of luminogens with dual‐state emission (DSEgens) that are brightly emissive in both the solution and solid state, with solvatochromism properties, by constructing a partially shared donor–acceptor pattern based on a twisted molecule. The DSEgens with bright fluorescence emission in both the solid and solution state demonstrate a unique solvatochromism behaviour depending on solvent polarity and thus may have applications in anti‐counterfeiting. Abstract : Twisted chemistry ! A general design strategy for a new class of luminogens with dual‐state emission (DSE) and solvatochromism properties by constructing a partially shared donor–acceptor pattern based on a twisted molecule was reported (see figure).
