Application:	4′-Chloro-2,2′:6′,2′′-terpyridine may be used in the preparation of the following: • mono- and bis-terpyridines • bis-hydroxy-functionalized terpyridine cadmium(II) complex and a fullerene derivative • 4-functionalized 2,2´:6´,2´´-terpyridines, building blocks for novel supramolecular structures, such as double helicates, dendrimers, micelles and metallo-supramolecular polymers
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. Molecules assemble themselves into stacked columns along the b axis, with an interplanar distance of 3.51Å. 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.
