The cover picture shows the optimised geometry, the electron density difference map for the HOMO–LUMO transition, and the simulated and experimental electronic absorption spectra of a nickel(II) 5,10‐diiminoporphodimethene molecule—a new type of porphyrinoid in which the macrocycle is electronically partitioned into tri‐ and monopyrrolic units. Examples of this porphyrinoid were prepared by palladium‐catalysed coupling of the 5,10‐dibromoporphyrin with alkyl carbazates, as reported by D. Arnold and co‐workers in their Full Paper on page 813 ff.
