Abstract

The detection of latent fingure prints (LFTs) are a significant step in forensic science. The visualization of LFTs are necessary to investigate the crime scene and footprint of criminals. On this connection, in recent years’ aggregation induced emissive (AIE) are emerged as potential luminescent materials of their potential use in fingerprint detection. Herein, we designed and successfully synthesized 4-imino-2-(methylthio)-8-(1,2,2-triphenylvinyl)-4H-benzo[4,5] thiazolo[3,2-a] pyrimidine-3-carbonitrile (TPE-2) AIEgen bearing –SCH₃ donor and –CN acceptor subunits. The photophysical, optical and AIE properties were investigated. The AIE properties was established in the DMSO (as good solvent) and water (as a poor solvent) mixture with various water fraction ranging from 0 to 95 %. Moreover, TPE-2 material was successfully utilized in fingerprint visualization and in anti-counterfeiting technology. The AIEgen TPE-2 paves a new way in advanced forensic and data security applications.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
