Onion-Shell Metal−Organic Polyhedra (MOPs): A General Approach to Decorate the Exteriors of MOPs using Principles of Supramolecular Chemistry
摘要:
Metal-organic polyhedra with surface-exposed organic groups have been designed. The polyhedra are based on concentric shells of alternating negative-positive-negative charges and have been used to design homochiral hosts.

A non-photochemical route for the regioselective and quantitative preparation of rtct-pyridylcyclobutane isomers is achieved from the combination of solid state [2+2] photoreactions and controlled isomerisations promoted either by Lewis or Brønsted acids under hydrothermal conditions.

Di- 1a and tetranuclear 1b metalâorganic squares have been obtained from bis- and tetra(pyridyl)cyclobutanes synthesized in the solid state, respectively; for 1b, a cyclobutane with two different metal binding subunits supports the formation of a polygon and polyhedron.

A linear template is used to direct the synthesis of a "head-to-head" tetrapyridine in the solid state, which, in a second step, assembles with a transition-metal-ion to form a polyhedral metal-organic host with a structure that conforms to a trigonal antiprism. The application of the linear template is reminiscent of the synthetic strategy of nature.
