Porphyrin-LEGO®: synthesis of a hexafullereno-diporphyrin using porphyrins programmed for [4+2]-cycloaddition.

A hexafullereno-diporphyrinoid was obtained in a sequence of cycloaddition steps using porphyrins programmed for [4+2]-cycloaddition reactions and C(60)-fullerene.

"Naked" iron-5,10,15-triphenylcorrole on Cu(111): observation of chirality on a surface and manipulation of multiple conformational states by STM.

A new member of the metalloporphyrinoid class, the one-carbon short corrole, has been developed in the past decade to a very accessible and easily tunable compound with many potential applications in material science and catalysis. Other than for the structurally related iron porphyrins, all attempts to prepare and study the "naked" iron triphenylcorrole molecule (FeTPC) in bulk have failed. Here, we demonstrate stabilization of FeTPC as adsorbates on a surface.
