Abstract

original image

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.
