Facile assembly of an efficient CoOx water oxidation electrocatalyst from Co-containing polyoxotitanate nanocages

Abstract

Head-to-tail and head-to-head [2+2] photodimerization of an unsymmetrical olefin containing benzimidazole and pyridyl groups was achieved by irradiating Ag(I) complexed olefin in crystalline state and gel state, respectively, in stereoselective manner. The [2+2] reaction indicates that the molecular arrangement in a gel is different from that of a xerogel. © 2013 The Royal Society of Chemistry.
