Introducing more electron withdrawing groups in acceptor unit at D-A type conjugated polymer boosts the effect of fast charge carrier transport and tuning energy level. However, there has been a lack of understanding the correlation between the halogen substituted molecular structure and solid-state packing status on the charge transport, particularly with conjugated polymer containing benzo[2,1,3]thiadiazole (BT) as the acceptor moiety and 4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b’]dithiophene (CDT) as a donor moiety with chlorine atom. Moreover, the chain alignment method using nanogroove facilitates hole mobility into 10 times faster than the pure system by grooving them. Also, different regioregularity induces the significantly dissimilar effect of the nanogroove and capillary force on the orientation of fibers and charge transport of the polymers. |
