Due to its physiological relevance, there is a growing need for improved optical sensors that can detect Cl-ion in biology and environmental samples. Herein, we have developed a new N-acylhydrazone substituted BODIPY-mercury(II) based fluorescent turn-on sensors 1-Hg 2+ and 2-Hg 2+ , which showed remarkable selectivity and specificity towards Clion under physiological conditions. The new BODIPY compounds 1 and 2 were synthesized by treating their corresponding 3,5-diformyl BODIPYs 3 and 4 with isonicotinohydrazide in one step under simple reaction condition. The compounds 1 and 2 absorb in 615-650 nm and emit in 625-660 nm regions. BODIPYs 1 and 2 showed exclusive sensing towards Hg 2+ and forms 1-Hg 2+ and 2-Hg 2+ complexes respectively which resulted in the quenching of fluorescence. The Job's plot analysis and HR-MS studies supported the formation of 1-Hg 2+ and 2-Hg 2+ complexes. The complexes 1-Hg 2+ and 2-Hg 2+ were found to be exclusive fluorescence turn-on sensors for chloride ion.
