4'-CHLORO-2,2':6',2''-TERPYRIDINE Chemical Properties,Usage,Production

Chemical Properties

brown crystalline powder

Uses

4'-Chloro-2,2':6',2''-terpyridine is widely utilized in the field of supramolecular chemistry, which is used to manufacture double helicates, dendrimers, micelles and metallo-supramolecular polymers. It is used to synthesize the mono- and bis-terpyridines. It is actively involved in Williamson type ether reactions alpha,μ-bishydroxy-functionalized poly(propylene oxide).

General Description

4′-Chloro-2,2′:6′,2′′-terpyridine (4′-Cltpy, Cltpy, Cl-terpy) is a tridentate ligand that contains a terpyridine (tpy) site with a Cl site at the 4 -position. It coordinates with various metal ions through these two sites to form different coordination polymers. Crystal structure study shows terpyridine unit of Cltpy adopts a trans, trans conformation. Mol-ecules assemble themselves into stacked columns along the b axis, with an inter-planar distance of 3.51?. It undergoes Williamson type ether reactions with α,ω-bishydroxy-functionalized poly(propylene oxide). It undergoes Williamson type reaction with α-hydroxy-ω-carboxy-functionalized poly(ethylen-oxide) to afford monoterpyridine terminated telechelics.
