BENZIMIDAZOLE - PYRIDINE: A NEW TYPE OF HGHLY SENSITIVE CHEMOSENSOR FOR ZN2+
Abstract
Discovery of new chemosensors for M2+ cations represent a continuously and challenging issue for researcher because of their potential applications in nano and micro technologies. Among the other metals, zinc is the second most abundant transition metal ion in human body and plays a crucial role in many biological and environmental processes. In this work we present the design, synthesis and characterization of a Zn2+ chemosensors and its coordination complexes based on podants with benzimidazole - pyridine skeleton. The new chemosensor have in the same molecule a ?-reach heterocycles (benzimidazole) and a p-deficient heterocycles (pyridine) connected via a methylene linker. The complexation ability of our podant with Zn2+ was investigated. The chemosensor proved to be highly sensitive for Zn2+ in the nanomolar range.
