A pyrene-based small molecular weight probe, exhibiting aggregation enhanced excimer emission has been synthesized. The crystalline emissive form detects 2,4,6-trinitrophenol (picric acid) at parts-per-billion concentration in solution and as low as 0.46 attogram in direct contact mode, operating predominantly in a static quenching mechanism, proposed on the basis of steady state and life-time fluorescence measurements.
一种基于芘的小分子量探针已被合成，它表现出聚集增强的准分子发射。这种晶体发射形式能在溶液中以十亿分之一的浓度检测2,4,6-三硝基苯酚（苦味酸），在直接接触模式下低至0.46阿托克，主要通过基于稳态和寿命荧光测量提出的静态猝灭机制进行检测。
