英文摘要	herein we propose a facile strategy to prepare nanowires and nanowire "shish-kebab" (nwsk) structures by controlling the crystallization behavior of all-conjugated rod-rod diblock copolymers poly[(p-phenylene)-block-(3-hexylthiophene)]s (ppp-b-p3ht (bmtn)) with varying main chain lengths. depending on the block length and ratio (i.e., ppp/p3ht, abbreviated as b/t), nanowires with low b/t ratios (copolymers with long p3ht blocks; b8t32 and b14t34) and nwsks with high b/t ratios (copolymers with long ppp blocks; b29t9 and b39t18) were formed for ppp-b-p3ht all-conjugated diblock copolymers. the formation of nanowires is governed by a strong interchain p-p stacking similar to the p3ht homopolymer, with an edge-on orientation of the p3ht moiety, whereas nwsks are formed as a result of the particular face-on molecular orientation of ppp moiety. as the length of the p3ht moiety was increased (the block ratio of ppp/p3ht reduced), the nwsks were transformed into nanowires gradually because of the decreasing density of "kebabs". for diblock copolymers with high ppp/p3ht ratios, the transition of the molecular orientation from face-on to edge-on was obtained by thermal annealing.
