Visualization of latent fingerprints using an AIE-active unsymmetrical azine: 2-Naphthol-pyrrole acrylate conjugate and its fluorescent sensing of Cu2+ and S2− ions, smartphone and logic gate applications

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

“…Among one such study, Tharmalingam et al reported an AIE-active unsymmetrical azine, 62 , by simple condensation of ethyl-α-cyano-5-formyl-2-pyrroleacrylate and 1-(hydrazonomethyl)naphthalene-2-ol and used it for the detection of Cu 2+ ions. 120 The red-emissive azine was further utilized for practical application in imaging latent fingerprints (LFPs). LFPs were demonstrated by accumulating the thumb impressions on the TLC plate surface and coated with the aggregated mixture of 62 in DMSO containing 60% water.…”

Real-time visualization of latent fingermarks with level 3 details based on a solid state emissive organic fluorophore using the powder dusting method

“…2,8,25–29 However, most of the articles discussed only level 1–2 details with organic fluorophores and took longer time (>5 min) to develop LFM images. 30–35…”
