Templated assembly of a pseudorotaxane of gold rectangles.

A nanoscopic pseudorotaxane (1)2 subset2 composed of the gold rectangle [Au4(mu-PAnP)2(mu-bipy)2](OTf)4 and the linear template 4,4'-bis(9''-anthryl)biphenyl was assembled (PAnP = 9,10-bis(diphenylphosphino)anthracene); bipy = 4,4'-bipyridine).

Self-assembly, structures, and solution dynamics of emissive silver metallacycles and helices.

Reactions of 9,10-bis(diphenylphosphino)anthracene (PAnP) and AgX (X = OTf-, ClO4-, PF6-, and BF4-) led to luminescent Ag-PAnP complexes with rich structural diversity. Helical polymers [Ag(mu-PAnP)(CH3CN)X]n (X = OTf-, ClO4-, and PF6-) and discrete binuclear [Ag2(mu-PAnP)2(CH3CN)4](PF6)2, trinuclear [Ag3(mu-PAnP)3 supersetBF4](BF4)2, and tetranuclear [Ag4(mu-PAnP)4 superset(ClO4)2](ClO4)2 metallacycles were isolated from different solvents. The tri- and tetranuclear metallacycles exhibited novel puckered-ring and saddlelike structures.

Self-assembly and molecular recognition of a luminescent gold rectangle.

A luminescent molecular rectangle [Au(4)(micro-PAnP)(2)(micro-bipy)(2)](OTf)(4) (1.(OTf)(4)) (PAnP = 9,10-bis(diphenylphosphino)anthracene, bipy = 4,4'-bipyridine, X = NO(3)(-) or OTf(-)), synthesized from the self-assembly of the molecular "clip" Au(2)(micro-PAnP)(OTf)(2) and bipy, shows a large rectangular cavity of 7.921(3) x 16.
