Sensing behavior and logic operation of a colorimetric fluorescence sensor for Hg 2+ /Cu 2+ ions

A Pyrazolo Imine‐based Colorimetric and Turn‐on Fluorescent Sensor Probe for Determination of Hg2+ Ion and its Application in Test Paper Strips

“…Moreover, Schiff base-based sensor probe for detection of mercury ion showed an obvious advantages such as simple single step reaction, short reaction time, simple procedure, inexpensive catalyst, good yields, high sensitivity and selectivity, lowcost, low response time and nondestructive character. Furthermore, the sensor ligand containing nitrogen, oxygen and sulfur atoms is considered as an ideal feature for using as a coordination site with mercury ions in fluorescent sensors (31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41). Inspired by the previous work of synthesis of a simple pyrazolebased Schiff base derivative fluorescent sensor through the condensation reaction of 5-amino-3-methyl-1-phenyl pyrazole and substituted salicylaldehyde using ethanol medium and its sensing property toward different metal ions (42), we carried out the present work.…”

Cinnamaldehyde‐Based Chemosensor for Colorimetric Detection of Cu2+ and Hg2+ in a Near‐Perfect Aqueous Solution

“…On the contrary, colorimetric detection using chemosensors has been known as a cost‐effective tool due to easy detection via naked‐eye without expensive equipment . Thus, it is really needed to develop effective and selective colorimetric chemosensors for metal ions …”
