TLDR
This critical review covers advances in anion complexation chemistry related to receptors based on organic frameworks in the years 2005-2006 and includes a discussion of anion templated assembly.Abstract:
This critical review covers advances in anion complexation chemistry related to receptors based on organic frameworks in the years 2005–2006. The review covers anion receptors that employ amides and thioamides, pyrroles and indoles, ureas and thioureas, ammonium, guanidinium, imidazolium, and receptors containing hydroxyl groups. There is a discussion of anion templated assembly, followed by a short section outlining modelling studies of these systems. (226 references.)read more
