Mesoscopic globular self-assemblies of platinum(II) complexes containing porphyrins

Slow evaporation of an acetone or chloroform solution of the novel tetranuclear platinum(II) complex [Pt(Lau(2)dim)Me](4)-(TpyP)(CF3SO3)(4) [Lau(2)dim = didodecyldiimine; TpyP = 5,10,15,20-tetrakis(4-pyridyl)-21H,23H-porphyrin] on a glass surface affords globular micrometric sized aggregates.
