Structurally defined,all conjugated polymers were chemically synthetized us
ing the Stille cross-coupling reaction. Their structure consisted in an alt
ernation of 2,2'-bipyridine and regioregular 3-octylthiophene oligomers whi
ch contained 4 or 6 thienyl rings. The NMR, UV-Visible and electrochemical
characterisations are also reported.
