Abstract:

A set of 4'-substituted 2,2':6',2''-terpyridines has been synthesized in a one-pot procedure under environmentally friendly reaction conditions using PEG and aqueous ammonia as solvents. This procedure features a short synthetic route, short reaction times, easy work-up, and good yields in comparison to conventional methods. The crystallographic data reveal the influence of the 4'-aryl substituent on the molecular structure and p-stacking behavior of the respective terpyridines.
