Fluorescent polyhydroquinoline (PHQ) derivative was fabricated utilizing one-pot engineered course. The PHQ derivative indicated aggregation induced emission enhancement (AIEE) with arrangement of nanoaggregates of size 11-13 nm in 95% watery DMF medium. The fluorescence emission of PHQ nanoaggregates was extinguished by including TNP and Cr (VI). They indicated prevalent fluorescence quenching towards both TNP and Cr (VI) over other meddling nitro-compounds and metal particles. In light of results got we presumed that both photo-induced fluorescence quenching of PHQ nanoaggregates by TNP, while Inner Filter Effect (IFE) was in charge of fluorescence quenching of PHQ nanoaggregates by Cr (VI). The PHQ nanoaggregates empowered identification of TNP and Cr (VI) down to 0.66 μM (TNP) and 0.28 μM (Cr (VI)). The use of PHQ nanoaggregates were reached out for location of TNP and Cr (VI) in genuine water tests.

聚氢喹啉纳米聚集体：双荧光探针，用于检测2,4,6-三硝基苯酚和铬（VI）。

荧光聚氢喹啉（PHQ）衍生物是利用一锅工程程序制造的。PHQ衍生物表明在95％含水DMF介质中具有11-13 nm大小的纳米聚集体排列的聚集诱导发射增强（AIEE）。通过加入TNP和Cr（VI）可以消除PHQ纳米聚集体的荧光发射。他们指出，与其他杂合的硝基化合物和金属颗粒相比，TNP和Cr（VI）普遍存在荧光猝灭。根据结果​​，我们推测两种光诱导的TQ对PHQ纳米聚集体的荧光猝灭，而内滤效应（IFE）负责Cr（VI）对PHQ纳米聚集体的荧光猝灭。PHQ纳米聚集体可鉴定低至0.66μM（TNP）和0.28μM（Cr（VI））的TNP和Cr（VI）。
