Pyrene-functionalised alternating copolyimide for sensing nitroaromatic compounds
journal contribution
posted on 2023-06-09, 12:57 authored by Stefano Burattini, Howard M Colquhoun, Barnaby GreenlandBarnaby Greenland, Wayne Hayes, Mathew WadeA novel, pyrene-functionalised copolymer has been synthesised in a single step via imidisation of poly(maleic anhydride-alt-1-octadecene) with 1-pyrenemethylamine, and its potential for the detection of volatile nitro aromatic compounds (NACs) evaluated. The new copolymer forms complexes in solution with NACs such as 2,5-dinitrobenzonitrile, as shown by 1H NMR, UV-vis and fluorescence spectroscopy. Moreover, thin films of this copolymer, cast from THF solution, undergo almost instantaneous fluorescence quenching when exposed to the vapour of 2,5-dinitrobenzonitrile (a model for TNT) at ambient temperatures and pressures.
