Inner- and peripheral-metal complexation behaviors of 5,10,15-tris(pentafluorophenyl)-20-pyrrolyl N-confused porphyrin (5) and its meso-pyrrolyl-bridged dimers (6-Ni and 7-Ni) were studied in this work. The resulting inner-Ag and peripheral-BF2 compl

Metal–organic frameworks (MOFs) composed of zirconium (Zr6) and N-confused porphyrins (NCPs) were synthesized. The cubic structures with ftw topology were determined by powder X-ray diffraction and microscopic analyses. These complexes represent hi

Copper complexes of corroles have recently been a subject of keen interest due to their ligand non-innocent character and unique redox properties. Here we investigated bis-copper complex of a triply-linked corrole dimer that serves as a pair of dival
