Abstract

Abstract : Photochemistry An all ‐ ortho fluorinated tetraaryldistyrylbenzene exhibits aggregation‐induced emission characteristics—in contrast to its hydrocarbon analogue, fluorine substitution stabilizes the AIEgen with respect to photocyclization. Instead, E / Z ‐isomerization is observed under UV irradiation in solution as an alternative relaxation pathway, whereas the title compound is stable as a rock in the crystalline state.
