Polymer Building Blocks:  Self-Assembly of Silver(I) Cyclotriphosphazene Cationic Columns

Abstract

The multimodal ligand hexakis(2-pyridyloxy)cyclotriphosphazene (L) and its 4-methyl-2-pyridyloxy analogue (MeL) react with Ag(I) to afford {[AgL]+}infinity supramolecular cationic columns via self-assembly, with the anions occupying the intercolumnar channels. In contrast, the reaction of MeL with Cu(I) yields a dimetallic Cu(II) complex containing mu-OH and mu-4-methyl-2-pyridyloxylato bridges.
