Europium(III) Macrocyclic Chelates Appended with Tyrosine-based Chromophores and Di-(2-picolyl)amine-based Receptors: Turn-On Luminescent Chemosensors Selective to Zinc(II) Ions.

Invited for this month's cover are the collaborating groups of Dr. Goran Angelovski from the Max Planck Institute for Biological Cybernetics in Tuebingen, Germany and Prof. Carlos Platas-Iglesias from Centro de Investigacións Científicas Avanzadas (CICA) and Departamento de Química, Facultade de Ciencias, Universidade da Coruña, A Coruña, Spain. The cover image shows chameleon-like molecules whose luminescence emission can be enhanced selectively and strongly by the coordination of zinc(II) ions.
