Solvation-dependent switching of solid-state luminescence of a fluorinated aromatic tetrapyrazole

Abstract

Creating stimuli-responsive materials with switchable solid-state luminescence remains a challenge. We report that the solvation of a novel organic fluorophore can be utilized to prepare such a material, which emits in the blue (442–446 nm) region when wet and in the green (497–503 nm) region when dry.
