A redox active 2-aza-anthraquinone unit was conjugated with 1,10-phenanthroline chelating units to give a dimetallic Ir(III) complex. The complex shows 'switch on' luminescence upon reduction of the azaanthraquinone bridge in turn revealing a highly visual colourimetric response.

Abstract

A redox active 2-aza-anthraquinone unit was conjugated with 1,10-phenanthroline chelating units to give a dimetallic Ir(III) complex. The complex shows 'switch on' luminescence upon reduction of the azaanthraquinone bridge in turn revealing a highly visual colourimetric response.
