Abstract In the corrole homologue, 6,11,16‐triarylbipyricorrole, the bipyrrole unit is replaced by a 2,2′‐bipyridine unit. This modification effectively alters the corrole N4 coordination sphere from the trianionic [(NH) 3 N] to the monoanionic [N 3 NH] state. The newly formed monoanionic core stabilizes Zn II ions with enhanced emission properties. The enhanced emission was further utilized for metal ion sensing studies and exploited for the selective detection of Zn II ions.
