Chalcone scaffolds as photo functional hybrid material of indolin-2-one functionalized siloxy framework for optical sensing of Cu2+

Abstract

Owing to their easy approachability and high degree of structural and functional diversity, many multicomponent reactions like 1,3-dipolar cycloaddition have been a rich source of conjugate π-systems, functionalised chromophores active molecules. Despite their high explorative potential and practical benefits, only a few products have been so far scrutinized for their metal sensing abilities. In the present report, indolin-2-one chalcones bearing siloxy molecular systems have been synthesized by [2+3] cycloaddition based sequence. Designed chemosensor exhibited optical (absorption spectra) response toward Cu2+ ion in acetonitrile solution. Different aspects of the sensing phenomena such as selectivity, association constants, etc were studied in detail using UV-Vis spectroscopy. The calibration plot is linear (r2: 0.9966) over the large Cu2+ ions concentration ranges (10 µM). This novel effort is initiated a well-organize way of efficient cationic sensor improvement with triazole for heavy metallic pollutants in environmental and health-care fields in large scales.
