图文摘要：以乙醇为良溶剂，水为不良溶剂，通过再沉淀法可得到表面光滑的TPDP纳米纤维。在自组装过程中，在两亲分子饱和溶液中加入水时，两亲分子首先组装成针状小棒。随着自组装时间的增加，产生了大量的纳米纤维。在用光学显微镜对其生长进行直接原位监测的过程中揭示了组装行为。亮点：合成了黑色右指向指针 2,3,6,7-Tetramethoxy-9,10-di(4-pyridyl)-9,10-dihydroanthracen (TPDP)。Black-Right-Pointing-Pointer TPDP纳米纤维可以通过再沉淀法获得。Black-Right-Pointing-Pointer 组装行为通过光学显微镜进行原位监测。-- 摘要：我们对新合成的两亲性 TPDP 分子的微观自组装过程进行了研究。可以看出，以乙醇为良溶剂，水为不良溶剂，再沉淀法可以得到表面光滑的纯TPDP纳米纤维。在自组装过程中，在两亲分子饱和溶液中加入水时，两亲分子首先组装成针状小棒。随着自组装时间的增加，产生了大量的纳米纤维。在用光学显微镜直接原位监测其生长的过程中揭示了组装行为。

Water-inducing molecular self-assembly of amphiphilic molecules into nanofibers

Graphical abstract: TPDP nanofibers with smooth surfaces can be obtained by reprecipitation method using ethanol as good solvent and water as poor solvent. In the self-assembly process, during the water adding to the amphiphilic molecules' saturated solution, the amphiphilic molecules firstly assembled into needle-like small rods. With an increase in the self-assembled time, a large number of the nanofibers are produced. The assembly behavior was revealed in the course of direct in situ monitoring of its growth with optical microscopy. Highlights: Black-Right-Pointing-Pointer 2,3,6,7-Tetramethoxy-9,10-di(4-pyridyl)-9,10-dihydroanthracen (TPDP) was synthesized. Black-Right-Pointing-Pointer TPDP nanofibers can be obtained by reprecipitation method. Black-Right-Pointing-Pointer The assembly behavior was revealed in situ monitoring with optical microscopy. -- Abstract: We present investigations on the microcosmic self-assembly process of new synthesized amphiphilic TPDP molecules. It can be seen that pure TPDP nanofibers with smooth surfaces can be obtained by reprecipitation method using ethanol as good solvent and water as poor solvent. In the self-assembly process, during the water adding to the amphiphilic molecules' saturated solution, the amphiphilic molecules firstly assembled into needle-like small rods. With an increase in the self-assembled time, a large number of the nanofibers are produced. The assembly behavior was revealed in the course of direct in situmore » monitoring of its growth with optical microscopy. Field emission scanning electron microscopy was adopted to characterize the morphologies of the products.« less
