Research Abstract

Discrete homo Cu-Cu-Cu and hetero Cu-Pd-Cu or Cu-Co-Cu metal arrays are prepared within an organic-pillared coordination box by inserting M(II)-azaporphine/porphine cartridges (M=Cu(II), Pd(II) or Co(II)), where the metal arrays show unique spin interactions in ESR : in particular, Δms=3 for the Cu-Cu-Cu array.
