Abstract

Oligo-tridentate ligands based on alternating pyridines and pyrimidines were synthesised by Stille-type carbon-carbon bond-forming reactions. The terpyridine-like sites are designed to coalign upon metal complexation, giving rise to organized and rigidly spaced metal ions. Peripheral functionalization of the basic bis-tridentate framework was explored. The heterocycles in the ligands are in an all-trans conformation about the interannular bonds ...
