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.
