Spin alignment of orthogonal pi-radicals of directly meso-linked porphyrin arrays.
High-spin states of poly pi-radical cations of directly meso-linked Zn(II)porphyrin arrays were observed by ESR spectroscopy because of the stabilization of the high-spin states by sterically orthogonal alignment of adjacent pi-radicals.
