title: Self-Assembly Process of Dodecanuclear Pt(II)-Linked Cyclic Hexagon.
abstract: The self-assembly process of a Pt(II)-linked hexagonal macrocycle consisting of six linear dinuclear Pt(II) units and six organic ditopic bent ligands was investigated. The process was monitored by (1)H NMR, and the intermediates in the self-assembly were analyzed by the n-k analysis. It was found that a 1:2 complex of a dinuclear Pt(II) unit and an organic ditopic ligand was exclusively observed as an intermediate with a certain lifetime and that the reaction of the 1:2 complex is the rate-determining step in the supramolecular macrocycle formation. The key 1:2 complex was unambiguously characterized by (1)H and DOSY NMR and ESI-TOF mass measurement.
