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.
[2+2] Photodimerization of Stilbazoles Promoted by Oxalic Acid in Suspension
waxy or even insoluble stilbazoles. Moreover, the oxalicacid loading could be lowered to sub-stoichiometric amounts. When further optimizations were needed, our strategy was found to be highly flexible to identify other oligocarboxylic acids as alternative additive to improve or even overturn regioselectivity. Oxalicacid and other oligocarboxylic acids were found to be capable of orienting more than
