Molecular level alignment of components and optimum morphology of hybrid materials are of great interest in many applications. Morphology control has been extensively used as a direct tool in the evaluation of interactions and assemblies of components in thin films. It is believed that preparation method and composition are powerful tools to direct the morphology, particularly in self-assembled systems such as fullerene-based hybrid materials. The present report outlines a synergistic self-assembly of fullerenes (C(60)) and functionalized poly (p-phenylene) (PPP) to develop nanofibers with high aspect ratios. Nanostructured PPP-C(60) hybrids were prepared by direct casting of the dilute solution on solid substrates and on water under ambient conditions. The formation of whiskers with high aspect ratio and investigation of interesting photophysical properties are discussed. An amphiphilic PPP was used as a template for preparing nanohybrids of C(60) at ambient temperature and conditions.
在许多应用中，混合材料各组分的分子水平排列以及最佳形态备受关注。形态控制已被广泛用作评估薄膜中各组分相互作用和组装的直接工具。人们认为，制备方法和组成是引导形态的有力工具，特别是在基于富勒烯的混合材料等自组装体系中。本报告概述了富勒烯（C(60)）与功能化聚对苯撑（PPP）的协同自组装，以开发具有高纵横比的纳米纤维。通过在环境条件下将稀溶液直接浇铸在固体基板和水上，制备了纳米结构的PPP-C(60)混合材料。讨论了高纵横比晶须的形成以及有趣的光物理性质的研究。在环境温度和条件下，使用两亲性PPP作为制备C(60)纳米杂化物的模板。
