Key Points

The aim is to design water-soluble luminescent probes for the selective detection of hypochlorous acid (HOCl).
Synthesis of tacn- or pyclen-based macrocyclic complexes
Incorporation of extended thioanisolepicolinate antenna
Assessment of photophysical properties in solution
Eu(III) luminescence is efficiently sensitized by the designed probes
Tb(III) emission is significantly quenched due to back-energy transfer
The probes show potential for selective detection of HOCl in aqueous environments

Abstract

The synthesis and photophysical properties of tacn-or pyclen-based macrocyclic complexes featuring extended thioanisolepicolinate antenna are reported. These systems efficiently sensitize Eu(III) luminescence, whereas Tb(III) emission is quenched due to back-energy...
