4-Chloro-2,2:6,2-terpyridine

Application

4-Chloro-2,2:6,2-terpyridine is a versatile brown crystalline powder that plays a significant role in supramolecular chemistry. It serves as a tridentate ligand with a Cl site at the 4-position and is instrumental in the creation of double helicates, dendrimers, micelles, and metallo-supramolecular polymers. The compound's ability to coordinate with various metal ions enables the formation of diverse coordination polymers. Notably, its terpyridine unit exhibits a trans, trans conformation, contributing to the self-assembly of molecules into stacked columns with an inter-planar distance of 3.51 Å. Additionally, 4-Chloro-2,2:6,2-terpyridine is actively involved in Williamson type ether reactions, facilitating the synthesis of mono- and bis-terpyridines as well as reactions with alpha,μ-bishydroxy-functionalized poly(propylene oxide) and α-hydroxy-ω-carboxy-functionalized poly(ethylene oxide) to produce monoterpyridine terminated telechelics.
