Porosity-driven large amplitude dynamics for nitroaromatic sensing with fluorescent films of alternating D–π–A molecules

Author affiliations

Abstract

We report herein the structural properties and nitroaromatic sensing performances of fluorescent thin films formed by alternating donor–acceptor π-conjugated chromophores. The incorporation of a flexible one-dimensional alkyl chain in the chromophore backbone drastically accelerates by more than one order of magnitude the sensing dynamics for the detection of 2,4-dinitrotoluene (DNT) vapors.
