A 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 (1) H 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.
通过聚（马来酸酐-alt-1-十八碳烯）与1-芘甲胺的酰亚胺化反应一步合成了一种新型的芘官能化共聚物，并对其检测挥发性硝基芳烃化合物（NACs）的潜力进行了评估。如（1）H NMR、紫外可见光谱和荧光光谱所示，这种新型共聚物在溶液中与2,5-二硝基苯甲腈等NACs形成络合物。此外，从四氢呋喃溶液中浇铸而成的这种共聚物薄膜，在环境温度和压力下暴露于2,5-二硝基苯甲腈（TNT的模型）蒸汽中时，几乎会立即发生荧光猝灭。
