A novel colorimetric and fluorescent chemosensor for acetate ions in aqueous media based on a rhodamine 6G–phenylurea conjugate in the presence of Fe(<scp>iii</scp>) ions

Abstract

A novel colorimetric and fluorescent chemosensor based on a rhodamine 6G phenylurea conjugate showed highly selective and sensitive recognition toward acetate ions in H(2)O-CH(3)CN (1:1, v/v) with fluorescence intensity change and also clear color change from pink to colorless in the presence of Fe(III) ions.
