A selective ‘turn-on’ fluorescent chemosensor for detection of Al3+ in aqueous medium: Experimental and theoretical studies

Quantum chemical elucidation of the turn-on luminescence mechanism in two new Schiff bases as selective chemosensors of Zn2+: synthesis, theory and bioimaging applications

“…Within a wide variety of methods, luminescent chemosensors have attracted the attention of researchers for their simplicity, low cost, high selectivity and sensitivity, and are applicable in many elds such as medical diagnostics, living cells, environmental control and electronics. 7,10,11 Although there are other methods such as atomic absorption spectrometry, inductively coupled plasma mass spectroscopy, inductively coupled plasmaatomic emission spectrometry, UV-visible spectroscopy, 12 they do not allow analyte monitoring in situ and in real time, especially in biological systems. In luminescent chemosensor, the analyte recognition can be set from a change of color or intensity of the emission from the interaction with the analyte.…”

Crystal structure, Hirshfeld surface analysis and DFT studies of (E)-2-{[(3-chloro-4-methylphenyl)imino]methyl}-4-methylphenol

“…They are important for their photochromic properties and have applications in various fields such as the measurement and control of radiation intensities in imaging systems, optical computers, electronics, optoelectronics and photonics (Iwan et al, 2007). The present work is a part of an ongoing structural study of Schiff bases and their utilization in the synthesis of quinoxaline derivatives (Faizi et al, 2018), fluorescence sensors (Faizi et al, 2016;Mukherjee et al, 2018;Kumar et al, 2017Kumar et al, , 2018 and non-linear optical properties (Faizi et al, 2020). We report herein on the synthesis (from 2-hydroxy-5methylbenzaldehyde and 3-chloro-4-methylaniline), crystal structure, Hirshfeld surface analysis and DFT computational calculations of the title compound, (I).…”
