摘　　要：采用液相组装法通过改变组装条件制备了高结晶性、宽度为2μm、长度为10~40μm的1,4-二咔唑基苯一维微米线(BeCzMW).X射线衍射和选区电子衍射结果表明,BeCz分子沿着晶体[100]方向生长.通过扫描近场光学显微镜进一步发现,BeCzMW被紫外激光激发后产生的荧光被限域在一维结构中,并沿着一维方向进行传导.BeCzMW在420 nm处的光学损耗系数R=0.0628 dB/μm,表明BeCzMW具有良好的光波导性能.One-dimensional 1,4-dicarbazolylbenzene microwires(BeCzMW)with high crystallinity and uniform size were prepared with a liquid phase assembly method by changing the assembly conditions.The results of X-ray diffraction and selective area electron diffraction indicated BeCz molecules grew along the crystal[100]direction.Scanning near-field optical microscopy was used to find that the fluorescence from the BeCzMW excited with an ultraviolet laser was effectively confined in the nanowire structure and propagated along the one-dimensional direction.The optical loss coefficient of BeCzMW was 0.0628 dB/μm at 420 nm,indicating that BeCzMW has good optical waveguide performance.
