The cover picture shows the ability of benzoporphyrin derivatives to emit in the red zone of the UV/Vis spectrum when excited with green light; represented by the lighthouses of Barra (Aveiro) and Cabo Espichel (Lisbon) in Portugal. These lighthouses are also symbolic of the cooperation between the two research groups. The studied functionalized porphyrins showed a remarkable emission enhancement and sensing ability for Hg 2+ metal ions. The binding with Hg 2+ induced strong changes in the ground state allowing the application of these compounds as chromogenic and fluorogenic metal‐ion sensors. Gas‐phase studies using MALDI‐TOF‐MS analysis confirmed their sensing ability. Further details can be found in the Full Paper by M. G. P. M. S. Neves, C. Lodeiro, and co‐workers on page 1230 ff.
