Anions are ubiquitous in natural system and play crucial role in biological and ecological system for example phosphate anion which is a main component in nucleotides a building block of DNA, involved in phosphorylation such as energy storage and signaling pathways. In addition other ions with negative impact on the environment make it of importance to develop an efficient ,easy and inexpensive detection and monitoring system for such anions. Aminopyridines Schiff bases were synthesized efficiently using microwave assisted synthesis, characterized using spectroscopic and X-ray analysis. UV-vis and flourmetric titration were used to characterize them as sensitive and selective sensors for significant anions, such as cyanide. In this presentation we will discuss the colorimetric and spectroscopic characterization and the sensor properties of Schiff bases; N- Salicylidene-3-amino pyridine (3APNS) and N-salicylidene-2-amino pyridine (2APNS). The conditions, anion selectivity, binding constants and stoichiometry in addition to potential applications.
