Stable,Water-Soluble Pta-Based Ru-Ag Organometallic Polymers

摘要

One of the latest trends in supramolecular chemistry is the quest for reproducible methods to achieve controlled self-organization of discrete units to form homo-and heterome-tallic coordination networks,aggregates,and polymers.This development is based on the use of appropriate organic,inorganic,and organometallic building blocks that allow the synthesis of ID linear or twisted chains,2D squares and polygons,and 3D cubes and polyhedra.Among the organic spacers,nitrogen-based aromatic heterocycles are the most widely used due to their good donor properties and rigidity.These ligands can act as corner units(bipy,phen)and spacers(pyrazines,terpy,porphyrinates,tetraazamacro-cycles).
