Azocalix[4]arene-based chromogenic anion probes

Chuan‐Feng Chen, Qi-Yin Chen

Open publisher page 49 citations

Abstract

Azocalix[4]arene derivatives 1–5, with one or two azophenol chromophores and different binding sites, were found to allow not only for high selective and sensitive colorimetric detection but also easy colorimetric differentiation of F−, AcO− and H2PO4−, of similar basicity, depending upon the azocalix[4]arene structure, guest basicity and conformational complementarity between the host and guest.
