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2 μm、 长度为10~40 μm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.

Abstract:

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.
