Abstract

A luminogen (ITP-TPE) comprising isothianaphthene-bridged tetraphenylethene units was efficiently synthesized. Its unique extended π-conjugated structure allows for colorimetric and off/on fluorescent detection for Cu²⁺ with extremely high selectivity and sensitivity, by the formation of nonarylamine-based organic mixed-valence state.
