摘要： 用再沉淀法制备了1,4-二氰基萘（DCN）一维亚微米结构。通过改变制备条件分别得到了DCN的线状及管状一维结构。所制备的有机亚微米材料具有良好的结晶性，不同结构的生长取向存在一定的差别。由于DCN分子的有序堆积，亚微米结构的的发光比溶液的发光有一定的红移。通过对单根材料的表征发现，DCN亚微米结构具有良好的光波导性能。空心结构的光波导性能要明显优于实心结构，主要原因在于空气介质减小了光学损耗。

Abstract: Solid and tubular one-dimensional (1D) submicrometer scaled structures were prepared from naphthalene-1,4-dicarbonitrile (DCN) with a reprecipitation method. The DCN microstructures have good crystallinity, and the growth direction of the solid structures are different from those of the tubular ones. Because of the ordered molecular packing of DCN, the fluorescence emission spectra of the microstructures undergo a red-shift compared with that of DCN solution. The microstructures reveal good optical waveguiding properties, and the optical loss of the materials are reduced by the air medium in the tubular structures.
