“Turn-on” unsymmetrical azine based fluorophore for the selective detection of diethylchlorophosphate via photoinduced electron transfer to intramolecular charge transfer pathway

Aggregation-induced emission-active azines for chemosensing applications: a five-year update

“…Azinphos 93 The photoinduced electron transfer results in a turn-on emission at 495 nm in ACN due to nucleophilic substitution of DCP at the azine nitrogen close to the -OMe group giving rise to a new ICT state [Fig. 7C].…”

“…Thiagarajan's group synthesized a new unsymmetrical azine, 43 , and utilized it for the selective and sensitive turn-on detection of the nerve agent mimic diethylchlorophosphate (DCP) by two different mechanisms in different solvent systems [Table 3, entry 6]. 93 The photoinduced electron transfer results in a turn-on emission at 495 nm in ACN due to nucleophilic substitution of DCP at the azine nitrogen close to the –OMe group giving rise to a new ICT state [Fig. 7C].…”

Highly selective and sensitive chromogenic recognition of sarin gas mimicking diethylchlorophosphate

“…38 Based on this mechanism, several imine linkage chemosensors have been fabricated to identify these hazardous nerve agents, but they are still in the early stages. [39][40][41][42] However, most of the chemosensors that have been developed are based on arduous, costly, and lengthy-time synthesis processes. The development of affordable, observable, and handheld chromo-uorogenic chemosensors with a more straightforward design and one-step synthetic procedure would be suitable.…”
