The Front Cover shows chameleon‐like molecules whose luminescence emission can be enhanced selectively and strongly by the coordination of zinc(II) ions. An efficient luminescence response is observed from the molecules that consist of an azamacrocycle as the chelator for europium(III), tyrosine as the chromophore, and di‐(2‐picolyl)amine as the zinc(II) recognition moiety. The induced emission changes allow for the precise analysis of zinc(II) ions, thus establishing these complexes as viable chemosensors for biological applications.
