摘要

合成了侧链带有芴的聚丙烯酸芴酯(PFM)

在含40%三氟化硼乙醚的二氯甲烷混合电解质溶液中

直接阳极氧化PFM获得了自支撑交联网状的聚（聚丙烯酸芴酯） (CPFM)薄膜. 通过UV-Vis、FTIR和1H-NMR对CPFM结构进行了表征. 荧光光谱表明得到的聚合物薄膜CPFM在415 nm附近处具有强的荧光发射峰

表明聚丙烯酸结构的引入没有影响聚芴的蓝色发光性能并有利于提高聚合物薄膜的力学性能. TGA表明得到的CPFM薄膜具有良好的热稳定性.

Abstract

High quality freestanding polyfluorene network films were synthesized successfully in CH2Cl2 containing additional 40%(by volume) boron trifluoride diethyl etherate (BFEE) by direct anodic oxidation of its precursor polymer

a polyacrylate functionalized with fluorene

which was first obtained through radical polymerization of fluorenyl acrylate.The possibility of inter and intramolecular oxidation cross\|linking resulted in a crosslinked conjugated network microstructure.UV-Visible and FTIR spectra were used to study the structures of the polymers

respectively.According to the UV-Visible spectra of FM

poly(fluorenyl acrylate) (PFM) and cross-linked poly(fluorenyl acrylate) (CPFM)

the spectra of CPFM showed red-shifted absorption at 352 nm compared to those of FM and PFM

indicating higher conjugation length of the backbone of the polymer.In the FTIR spectrum of CPFM

three peaks at 800

754 and 720 cm-1 suggested that CPFM was 1

4trisubstituted.Furthermore

the maximum emission peak of PFM appeared at 346 nm while that of CPFM in solid state appeared at 415 nm

implying the blue-light emitting property of CPFM.Polyfluorene network films obtained from this medium showed good thermal stability.Scanning electron microscopic results indicated that network CPFM films composed of ordered nanostructures were obtained electrochemically in this paper.
