A new class of dual fluorescent chemosensors for nitroaromatic compounds (NACs) based on phosphonated pyrene derivatives is reported, showing high selectivity towards trinitrotoluene (TNT). The strong intermolecular interactions (π-π stacking and hydrogen bonding) allow high fluorescence quenching with visual detection in short response times.
报道了一类基于膦酸化芘衍生物的新型用于硝基芳香族化合物（NACs）的双荧光化学传感器，该传感器对三硝基甲苯（TNT）表现出高选择性。强烈的分子间相互作用（π-π堆积和氢键）使得在短响应时间内通过视觉检测实现高荧光猝灭。
