Terpyridines functionalized with thienyl substituents

What is it about?

This review deals with the synthesis and applications of 2,2':6',2''-terpyridines which are functionalized with thiophene ring, directly linked to the terpyridine core or via a spacer. Two main methodologies were used, ring closure of diketones and cross coupling reactions. The obtained compds. find applications in various fields esp. in material sciences such as solar cells or macromol. sciences
