Abstract

Abstract : A urea-based molecule behaving as a ditopic sensor for fluoride and cadmium. Abstract : A urea-basedBPC [1, 5-bis(perfluorophenyl)carbonohydrazide] molecule with four acidic NH protons has been synthesized by a facile synthetic process. The molecule was found to be a ditopic chemosensor for Cd 2+ and F − ions.BPC was synthesized from low-cost starting materials, dinitrophenyl hydrazine and triphosgene. The host–guest interactions between the ions (Cd 2+ and F − ) were not only confirmed by convenient spectroscopic techniques such as UV-Vis, PL, 1 H-NMR, FT-IR, and cyclic voltammetry but also through modern DFT, the results of which were in good agreement with the experimental results. In vitro studies in human cancer cells (HeLa cells) were successfully performed withBPC and Cd 2+ using fluorescence microscopy. The reversible UV-Vis response forBPC with F −, OH − and H + mimics multiple logic functions and can be used for several complex electronic circuits based on logic operations. The pH sensor (BPC ) can be further interfaced with suitable circuitry interfaced with appropriate programming for ease of access and enhancement of its practical applications.
