Abstract

Luminescent Aryl Naphthalene Sulfones have been prepared via Garratt-Braverman cyclization of γ-substituted bis-propargyl sulfones for explosive and pollutant 2,4,6-Tri nitrophenol (TNP) recognition in aqueous medium by fluorescence quenching. The quenching can be explained through AIE-ACQ-RET-ICT based mechanisms. In vitro detection of TNP has been performed inside pollen cells. In real time stepping, paper strip and pocket solution kit has been fabricated for on spot detection of TNP. Moreover as an analytical application TNP has been detected from several surface water specimens collected throughout West Bengal, India. The limit of detection has been found as low as 10 nM together with quenching constant as 6.8 × 105 M−1, which is even superior to the recently published sensor materials.
