A highly sensitive and selective pyridyl based colorimetric chemosensor (H2L) for the efficient detection of Ni(2+) has been reported. The synthesized chemosensor H2L is highly efficient in detecting Ni(2+) even in the presence of other metal ions that commonly co-exist with Ni(2+). H2L also shows distinct color change from green to deep red visible under(More)
Herein we report the selective detection of Cu2+ and SO3 2− by phenanthraquinone thiosemicarbazone (PQTSC) chemosensor. The chemosensor is efficient in detecting Cu2+ over other metal ions, while the PQTSC-Cu2+ complex selectively sense SO3 2− over other anions. On addition of Cu2+ to the receptor solution, quenching of emission intensity is observed by 16(More)
