Regioregularity (RR) has given strong influences on the properties of poly(3-hexylthiophene) (P3HT) which is the representative of conjugated polymer. Recently, some researches carried out the control of Mn, PDI, and regioregularity analyzed the property of polymers according to RR. But the systemic study in sequence of crystallizable unit has ignored because of lack of methodology for identifying. Therefore, we suggested that the regioregular-regiorandom P3HT block copolymer approach by using living characteristics of GRIM polymerization. We tuned the regioregularity in wide range by changing the ratio between first and second block. And we observed the unique properties of block copolymer occurred by sequential change of crystallizable unit. Although random copolymer and regioregular-regiorandom block copolymers were in the same RR, the crystallinity of block copolymer obtained relatively high values. Also above result were verified by their solution assembly behaviors through the formation of nanowires. Therefore, our findings could be guidelines for tailoring the behaviors of regioregular-regiorandom P3HT block copolymers.
