Abstract We describe conjugated polymers entwined around Cu I with alternating α- quaterthienyl (poly [Cu (T 2) 2]) or 3′, 4′, 3′′′′, 4′′′′-tetrahexyl-α-sexythienyl (poly [Cu (T 3) 2]) moieties and 1, 10-phenanthroline complexing sites. Our strategy is to synthesise the 2, 9-bis (oligothienyl)-1, 10-phenanthroline precursors, then to assemble these ligands by means of Cu I templating followed by electropolymerisation. Poly [Cu (T 2 ...
