We synthesised a rod-rod diblock copolymer, poly(3-((3<jats:italic>S<\/jats:italic>)-3,7-dimethyl-octyl)-thiophene)-block-poly(4-octyl phenylisocyanide) (<jats:bold>PTh-<\/jats:bold><jats:bold><jats:italic>b<\/jats:italic><\/jats:bold><jats:bold>-PPI<\/jats:bold>), composed of a \u03c0-conjugated polymer and a rod-type helical coiled polymer.
