Theoretical study on fluorescent probes for cyanide based on the indolium functional group
Source abstract
Abstract
A series of fluorescent probes were investigated to explore the mechanism of the detection for CN−, and all of the probes have an indolium group. The interaction between the functional group and the cyanide ion was simulated to examine the selectivity of these probes. The influences of some other anions were also tested in the cyanide detecting process. The different binding abilities between CN− and F− in aqueous solution were distinguished using the potential energy calculations in consideration of hydrogen bonding interactions. The large change of the emitting wavelengths of the fluorescent probes before and after the addition of CN− was explained through the analysis of the molecular orbital properties. The results indicate the large structural change results in a significant emission shift when each probe captures a cyanide ion. According to this conclusion, new fluorescent probes were designed.
