The ability to cover the face of a porphyrin macrocycle selectively is an attractive feature for concepts such as catalysis and anion binding that is reliant on porphyrin core interactions. Herein, we have synthesized a family of mono-urea functionalized porphyrin complexes with intent to investigate their potential to form coreπ interactions selectively to one face of the porphyrin macrocycle. By altering the distance between the urea moiety and the porphyrin through direct linkage or introducing a linker group we can control the formation of the core interactions. This is clearly seen in the crystal structure of 1-phenyl-3-(2-([10,15,20-triphenylporphyrinato]zinc(II)-5-yl)phenyl)urea where a unique face capping effect is demonstrated. In the crystal of this complex, there is a hydrogen-bonding network between the urea group and the axial methanol ligand forming head-to-tail aggregates with the Zn-O axis all molecules pointing in one direction.

In his pioneering work to unravel the catalytic power of enzymes, Warshel has pertinently validated that electrostatic interactions play a major role in the activation of substrates. Implementing such chemical artifice in molecular catalysts may help impr

The conversion of porphyrins bearing primary amines into zinc-protected azido porphyrins utilising a diazo-transfer reagent is reported. This method allows the mild, facile, and one-pot synthesis of zinc azido porphyrins bearing a range of meso functionalities, producing the required porphyrin in high yield. Reactivity of the azide functionality is demonstrated by subsequent model click reactions to produce triazole derivatives. Georg Thieme Verlag Stuttgart New York.
