| 中文摘要 | a series of donor acceptor (d a) conjugated polymers (cps) comprising dithieno[2,3-b;7,6-b]carbazole (c1) or dithieno[3,2b;6,7-b]carbazole (c2) as d unit and thienopyrroledione (tpd), isoindigo (iid), or diketopyrrolopyrrole (dpp) as a unit were synthesized, and their semiconducting properties were investigated with organic field-effect transistors (ofets). because of different bonding geometry of cl and c2, the cps based on these isomeric d units have distinct backbone conformation. the cps based on c1 unit and all three a units show strong backbone curvature. in consequence, these polymers all formed amorphous films and exhibited low ofet mobility in the level of 10(-3) cm(2)/(v s). p(tpd-c2) and p(dpp-c2), which comprise c2 and tpd or dpp, both display pseudo-straight-shaped backbones and formed ordered films with the polymer backbones adopting edge on orientation respective to the substrates. accordingly, p(tpd-c2) and p(dpp-c2) exhibited the highest mobility of 0.31 and 1.36 cm(2)/(v s), respectively. however, p(iid-c2) could only form amorphous films probably owing to its highly stiff backbone, leading to a moderate ofet mobility (2.96 x 10(-2) cm(2)/(v s)). this implies that large fused aromatics are promising building blocks for high mobility d a cps when polymer backbone conformation and rigidity are appropriately manipulated. |
