The cover picture shows a novel dual channel fluorescent probe for Ca 2+ and Zn 2+ based on a coumarin Schiff base. The probe displays a solvent dependent dual sensing, viz., recognition of Ca 2+ in DMF‐H 2 O (9∶1, V / V ) solution based on C = N isomerization, photoinduced electron transfer ( PET ) inhibition and chelation‐enhanced fluorescence ( CHEF ) mechanism as well as detection of Zn 2+ in H 2 O‐CH 3 OH (9∶1, V / V ) solution by excited‐state intramolecular proton transfer ( ESIPT ) and CHEF processes. More details are discussed in the article by Guo et al. on page 1263–1269.
