Sathiyan, Govindasamy; Mathivanan, Dhamodiran; Bhuvaneshwari, Balasubramaniam; Garg, Ashish; Gupta, Raju Kumar; Singh, Anand published an article in 2021. The article was titled 《Olefin-linked conjugated fluorescent oligomer: Design, synthesis, photophysical studies and detection of nitroaromatic compounds (NACs) in aqueous media》, and you may find the article in Sensors and Actuators, A: Physical.Safety of 4-Cyanobenzyl bromide The information in the text is summarized as follows:
The development of novel fluorescent polymers has attracted significant attention owing to their potential applications in energy and environmental sciences. This study reports novel oligomer (TRZBT) synthesis via Wittig-Horner reaction using bithiophene aldehyde and triazine tri-Et phosphite. The resulting oligomer possesses large porous morphol., which was confirmed using SEM anal. Further, the chem. structure of TRZBT was confirmed by FT-IR, NMR, and GPC studies. The triazine acceptor (A) unit linked with bithiophene donor (D) unit through olefin π-conjugation resulted in a Donor-π-Acceptor (D-π-A) type oligomer. Detailed studies of the solvent-dependent photophys. properties of TRZBT were performed. Due to the alternate D-A structure of oligomer, enhanced intramol. charge transfer (ICT) properties between D and A moiety was observed Further, TRZBT in THF and THF: H2O (10:90) system effectively detected nitro-explosives in aqueous media, which exhibited high sensitivity, selectivity, and quick response via fluorescence quenching. TRZBT showed a higher quenching constant (Ksv) value of 4.91 x 105 M-1 towards picric acid as compared with other nitroaroms. Significantly, the detection limit of 1.58 nM in a 100% aqueous medium confirms that the synthesized material can detect even trace levels of the analyte. The experimental part of the paper was very detailed, including the reaction process of 4-Cyanobenzyl bromide(cas: 17201-43-3Safety of 4-Cyanobenzyl bromide)
4-Cyanobenzyl bromide(cas: 17201-43-3) is a white solid. Its melting point is 113-117°C, and flash point is 125.1°C. It is insoluble in water at 20°C. It is stable under normal temperatures and pressures. It should be stored at 0-5°C.Safety of 4-Cyanobenzyl bromide
