A highly selective dual-channel Hg2+ chemosensor based on an easy to prepare double naphthalene Schiff base

A novel highly sensitive fluorescent probe based on Schiff base for Al<sup>3+</sup>

“…紫外吸收光谱与荧光光谱均显示L与Al 3+ 形成了 络合物. 为了确定L与Al 3+ 的结合模式, 通过等摩尔连 续变化法测定了Al 3+ 与L的结合比 [24] . 固定L与Al 3+ 的总 浓度为2´10 [11,12] , 计算出L与Al 3+ 的结合常数为1.07×10 5 M −1 .…”

A novel rhodamine-based fluorescence chemosensor containing polyether for mercury (II) ions in aqueous solution

“…While, some of them were operated in organic solvents or in aqueous solution of organic solvent, which limit their applications in organism. [24][25][26][27][28] Hence, the development of novel pure water soluble, sensitive and interference-free fluorescent chemosensors for Hg 2+ detection is still highly desired. Poly(ethylene glycol) methyl ether [PEG], which is a well-known nontoxic, flexible, and excellent water-soluble polymer, is widely used in pharmaceutical, cosmetic, food processing and other industries.…”

A Turn‐On Fluorescence Chemosensor for Cyanide in Aqueous Media Based on a Nucleophilic Addition Reaction

“…[25] Despite their toxicity, their outstanding applications in various industrial processes including electroplating, metallurgy, heap leaching of gold ore, polymer synthesis, steel manufacturing and as raw materials for synthetic fibers, resins and herbicides are inevitable, which raise the risk of accidental or intentional release of cyanide ions into the environment as a toxic contaminant. [30][31][32] In view of this requirement and as a part of our research interest in ion recognition, [33][34][35][36][37][38] we attempt to develop an efficient optical chemosensor which can sense CN  with specific selectivity and high sensitivity. [27][28][29] Sensitive, selective, simple, low-cost, and easy-to-prepare CN  fluorometric chemosensors have become good choices for various applications.…”
