The advent of methods for the construction of supramolecular assemblies provides a route to exploring the benefits of artificial allosteric catalysts. To expand our ability to control reactions using supramolecular catalysts capable of changing shape in response to chemical input signals, we report the development and high yield syntheses of multidomain(More)
The weak-link approach (WLA) to supramolecular assemblies allows for the design of multimetallic two- and three-dimensional arrays, host-guest architectures, sensors, catalysts, switches, and signal amplification devices. This Account describes the course of our investigations in this area beginning with the development of a chemical tool kit of building(More)
A novel bis(phosphinoalkyl-thioether)arene ligand with a fluorinated aryl group (1,4-(Ph(2)PCH(2)CH(2)S)(2)C(6)F(4)) has been synthesized. This ligand has been used to prepare symmetric bimetallic structures with Rh(I) and Ir(I) metal centers in high yield. Unlike their nonfluorinated counterparts, these complexes can be opened into large macrocyclic(More)
The ligand 1,4-bis[4-(diphenylphosphino)butyl]-2,3,5,6-tetramethylbenzene, 3, was used to synthesize a mononuclear Rh(II) complex [(eta(1):eta(6):eta(1)-1,4-bis[4-(diphenylphosphino)butyl]-2,3,5,6-tetramethylbenzene)Rh][PF(6)](2), 6+, in a two-legged piano-stool geometry. The structural and electronic properties of this novel complex including a(More)
