溶剂交换法制备一维有机纳米材料

Preparation of Organic Nanowires via Solvent Exchange Method

利用溶剂交换法制备了几种有机小分子化合物的一维纳米材料,并分别用SEM、TEM、XRD等对其结构进行了表征.分析了纳米材料的生长过程,讨论了有关的机理,并研究了其吸收光谱和荧光光谱等光物理行为.结果显示,有机纳米结构的形貌和尺寸对分子聚集体的光谱性质具有调制作用,使得它们展示出不同于溶液和体材料的优良纳米特性.

One dimensional orgarfic nanostructures were prepared via solvent exchange method and characterized by SEM, TEM and ED. The growth process of the nanowires was also analyzed and discussed. Their spectral properties were researched by UV-vis absorption and fluorescence spectrometers. The results showed that optical properties of molecular aggregates were strongly dependent on the morphology and size of the organic nanostructures. They performed distinct optical properties different from their solution and bulk materials.
