EurJOC is co-owned by 11 societies of ChemPubSoc Europe, a union of European chemical societies for the purpose of publishing high- quality science. All owners merged their national journals to form two leading chemistry journals, the European Journal of Organic Chemistry and the European Journal of Inorganic Chemistry. Three further members of ChemPubSoc Europe (Austria, Czech Republic and Sweden) are Associates of the two journals.

COVER PICTURE

The cover picture shows the tetranickel complex ofa rectangular porphyrin array with novel connec-tivity. Conjugating azo and butadiyne bridges linkthe opposite sides of the rectangle, and the absorp-tion spectrum demonstrates strong electronic com-munication between the chromophores. The syn-thesis and characterisation of this tetramer aredescribed in the article by D. P. Arnold et al. onp. 4381ff. The molecule is set against a back-ground of a sunset on the Great Barrier Reef,emphasising the role of porphyrinoid pigmentsin solar energy capture.
