Multi‐C−C/C−N‐Coupled Light‐Emitting Aliphatic Terpolymers: N−H‐Functionalized Fluorophore Monomers and High‐Performance Applications

“…The deficiency of copper in the body for prolonged periods causes anemia, hypothermia, and growth/mental retardation, whereas excess copper produces renal dysfunction, cirrhosis, hepatitis, tremors, mental deterioration, azotaemia, and congenital diseases . Thus, attempts have been made to discover cost‐effective, reliable, and simple techniques for detecting high and low concentrations of copper ions.…”

“…Fluorescence spectroscopy could enable the development of smarter detection tools for Cu II , because of its high sensitivity and selectivity, cost effectiveness, short response time, and low detection limit . In this context, few fluorescent probes/polymers have been developed for sensing Cu II , which has a pronounced quenching effect on fluorophores by mechanisms inherent to paramagnetic species . Additionally, Cu II has severe detrimental effects on the environment, and thus Cu II exclusion is crucial for its betterment…”

[13,15] Additionally,C u II has severe detrimental effects on the environment, andt hus Cu II exclusion is crucial forits betterment. [16] In view of this, five nonconventional, purely aliphatic, intrinsiccally fluorescent, multifunctionalt erpolymersh ave been prepared fort he first time by the CÀC/CÀN-coupled, NÀ H-functionalized polymerization of two non-emissive monomers with in situ generated protrusions of af luorescent tertiary amide monomer for use in four-in-one applications, namely Cu II sensing, high-performancer emoval of Cu II ,l ogic gates, and Madin-Darby canine kidney (MDCK) cell imaging.…”

Research Progress in Design, Synthesis and Application of Benzothiazole-Based Fluorescent Probes

“…由于是经羟汞化而水解 的特殊反应机理, 该探针具有良好的选择性. 在国内, 刘伟生课题组 [24] [26] , 用于检测 Cu 2＋ 的苯 并噻唑基探针也常被报道 [27,28] . 其中, 较为常见的是涉 及 HBT 结构的 ESIPT 型荧光探针 [21] .…”
