A highly selective and ratiometric fluorescent probe for cyanide by rationally altering the susceptible H-atom

Recent Progress in Metal–Organic Framework (MOF) Based Luminescent Chemodosimeters

“…Various methods have been developed for the quantitative analysis of CN − , including the titration method, electrochemical assays [160], chromatography [161], as well as the colorimetric and fluorogenic method [162]. Among these methods, the design and use of fluorescent probes for sensing CN − have received considerable attention [163,164,165]. The chemososimeters for CN − monitoring are normally associated, with several typical chemical reactions, including the cyanohydrin forming process, additions to the dicyano-vinyl group, michael addition, and indolium or pyridinium addition reactions.…”

Fluorescence Dyes for Determination of Cyanide

“…In 2017, Hao et al [77] designed and synthesized a probe CS8 having a naphthalimide unit as the fluorophore and a methylated trifluroacetamide moiety as the acceptor part, which can be employed for selective and ratiometric signaling of cyanide. The group also employed the probe to study the sensing recognition of cyanide using HPLC, UV-vis, and emission spectroscopic analyses.…”

A sensitive and selective BINOL based ratiometric fluorescence sensor for the detection of cyanide ions

“…[14][15][16][17][18][19][20][21][22][23][24][25][26][27] Among the uorescent probes, ratiometric probes have a unique advantage of emission at two different wavelengths providing a built-in correction for environmental effects. [28][29][30][31][32][33][34][35][36][37][38][39][40] The integral property of uorescence and chirality of 1,1 0binaphthol (BINOL) and its derivatives have made them potential candidates for asymmetric catalysis as well as uorescent chemosensors. [41][42][43][44][45][46][47][48] Additionally, the uorescence property and the host-guest interaction of these molecules can be manipulated by adding suitable substitution in the major or minor groove of BINOL.…”
