Sequence selective dual-emission detection of (i, i + 1) bis-phosphorylated peptide using diazastilbene-type Zn(ii)-Dpa chemosensor

Abstract

This paper describes a new fluorescent chemosensor for phosphorylated peptide, which comprises a rigid trans-4,4'-diazastilbene and two Zn(II)-Dpa (2,2'-dipicolylamine) units; this chemosensor sequence-selectively binds to a (i, i + 1) bis-phosphorylated peptide and displays a dual-emission fluorescence change.
