| 中文摘要 | new large-size poly(3-butylthiophene) (p3bt) spherulites are obtained by solution aging. these p3bt spherulites are composed of nanoribbons, and the p3bt molecules arrange into form ii structure with a backbone pi-stacking distance of 0.47 nm. p3bt lamellae adopt "flat-on" orientation at the edge of the spherulite, and the spherulite preferentially grows along the pi pi stacking direction. these spherulites could be obtained in bulk solution or at the top or bottom of the solution, depending on the competition of gravity and brownian motion. temperature-dependent photoluminescence spectra demonstrate that the polymer chains are arranged in h-aggregation model. the 00 transition in uvvisible absorption spectra blue shifts from 2.03 ev (610 nm, form i) to 2.11 ev (589 nm, form ii). these results provide a further understanding of the crystallization and photophysical properties of poly(3-alkylthiophene) (p3at), and the preparation method of large size and pure p3at spherulites shows potential in applications of organic electronics. |
