A highly selective fluorescent probe for colorimetric recognition of cyanide anion based on heptamethine cyanine-triphenylamine conjugate

Design of “turn-off” luminescent Ln-MOFs for sensitive detection of cyanide anions

“…Further comparison of the two Ln-MOFs revealed that the LOD value of 1 is lower than the permissible level of CN − specified by the World Health Organization (WHO) in drinking water (1.9 μM), but the LOD value of 2 was higher than the WHO value. 73,74 It indicates that 1 and 2 can effectively detect CN − with high sensitivity and selectivity. The ability to detect CN − in aqueous solutions was further investigated.…”

Computational Design, Synthesis, and Photochemistry of Cy7‐PPG, an Efficient NIR‐Activated Photolabile Protecting Group for Therapeutic Applications**

“…[45] From here on, functionalizing the meso-carbon with various nucleophiles has been demonstrated. [33,[45][46][47][48] Furthermore, the Suzuki cross-coupling of IR-786 derivatives has also been accomplished, [49][50][51] despite the low reactivity of the CÀ Cl bond (Scheme 1).…”

Triphenylamine-based small-molecule fluorescent probes

“…2) for the selective detection of CN − ions. 30 In this probe, one indolium group and the triphenylamine group act as fluorophores, but the electron-donating group of the indolium salt acts as a site of attack for the CN − ion. Probe 3 in both CH 3 CN and CH 3 CN/H 2 O (9/1, v/v) exhibits a strong emission peak at 780 nm, which decreases with the gradual addition of CN − ions.…”
