英文摘要	the crystallization-dominated and microphase separation/crystallization-coexisted structure of the all-conjugated diblock copolymers poly(2,5-dihexyloxy-p-phenylene)-block-(3-hexylthiophene) (ppp-b-p3ht, denoted as bmtn) with different block compositions was affected by the aggregation state of the diblock copolymers in solvents with different solubilities. for b34t66, b62t38, and b75t25, the coexistence of microphase separation and crystallization was obtained in good solvent with few crystalline aggregates. for b34t66 with a longer p3ht block, densely stacked fiber crystal structures in thin films were found by using marginal solvents with crystalline aggregations in solutions. as for b62t38 and b75t25 with shorter p3ht block and longer ppp block, crystal structures were obtained by the use of solvents with a much larger solubility difference of the two blocks. thus, microphase-separated structures are prone to form from solutions with coil conformation and fiber crystals from solutions with larger aggregates, which resulted in the increased crystallinity.
