Abstract

A multisignaling assay for the selective detection of Fe3+ ions with a cruciform-shaped alkynylpyrene (1) bearing four peripheral N,N-dimethylethynylaniline units is reported. Upon exposure to various metal ions, only Fe3+ showed significant changes in the optical, electrochemical, and electrochemiluminescent behaviors of 1.
