  Anion−π−π Interactions in a Dinuclear M₂L₂Metallocycle

  摘要：

  The combination of the square-planar cis-protected [Pt(dppp) (O3SCF3)(2)] (M) with the ditopic N, N'-bis(3,5-dimethyl-4-pyridinyl)-4-ethoxy-2,6-pyridinedicarboxamide ligand (L) leads both in solution and in the solid state to the quantitative self-assembly of a M2L2 metallocycle. We also report crystallographic evidence derived from the solid-state structure of the dinuclear metallocycle in support of the existence of anion-pi-pi interactions.

  A dinuclear self-assembled cationic macrocycle based on Pt(II)-N(pyridine) coordinative bonds and having competitive triflate anions, as metal counterions, is used in the construction of [2]rotaxane and [2]pseudorotaxane architectures assisted by hydrogen bonding. The kinetic lability of the Pt(II)-N(pyridine) coordinative bond controls the dynamics of the [2]rotaxane.

  [GRAPHICS]A series of heterodimeric tetralactam macrocycles have been self-assembled using two kinetically labile zinc porphyrin-pyridine interactions. The stability constants have been determined by UVvis titrations in CHCl(3). The stability constants depend on the degree of preorganization of the linker units connecting the interacting groups. The ability of the self-assembled macrocycles to bind a terephthalamide guest was also investigated. One of the macrocycles was used for the construction of a [2]rotaxane. The dynamic properties of this system provide insight into the exchange mechanisms that operate in complex noncovalent assemblies.
