On–off–on fluorescent oligomer as a chemosensor for the detection of manganese(<scp>vii</scp>), sulfur(<scp>ii</scp>) and aldehydes based on the inner filter effect

Abstract

In this article, a sensitive and selective on–off–on fluorescence chemosensor, Tyloxapol (one kind of water soluble oligomer), was developed for the label-free detection of MnO₄⁻ ions in aqueous solution.
