Triphenylamine-based fluorophores containing pyrene or corannulene show variable fluorescence quenching sensitivity toward nitro explosives. The most sensitive fluorophore is capable of detecting TNT on the ng cm−2 scale; the array is useful for identifying nitro aromatics.
含有芘或芫荽烯的三苯胺基荧光团对硝基炸药显示出不同的荧光淬灭灵敏度。最灵敏的荧光团能够检测到 ng cm-2 级的 TNT;该阵列可用于识别硝基芳烃。
