Abstract

A self-assembled crystalline microporous dendrimer framework (MDF) exhibits novel turn-on and ratiometric fluorescence upon exposure to solvent vapours. The donor–acceptor character, combined with the large surface area (>650 m² g⁻¹), allows the MDF to discriminate vapours of volatile solvents with turn-on and colour change of photoluminescence.
