本文报道了顺式和反式稀土聚乙炔用三氯化铁硝基甲烷溶液的掺杂.高量掺杂顺式和反式稀土聚乙炔[CH(FeCl_4)_y]_x的电导率(σ)可分别达到446Ω~(-1)·cm~(-1)和38Ω~(-1)·cm~(-1),并且电导率随时间衰减较慢,表明三氯化铁掺杂的稀土聚乙炔较稳定.低掺杂量聚乙炔红外光谱上900cm~(-1)和1400cm~(-1)处出现两个掺杂特征峰.掺杂量(y)小于0.02(摩尔分数)的样品顺磁共振谱上出现一窄一宽两峰.高掺杂聚乙炔的X-衍射峰变宽平;扫描电镜显示此掺杂量聚乙炔的形貌—微纤维集结无明显变化.
In this paper, the doping of cis and trans rare earth polyacetylene with ferric trichloride and nitromethane was reported.The electric conductivity (σ) of high content doped poly (acetylene) and trans-rare earth polyacetylene [CH (FeCl_4) Which can reach 446 Ω -1 cm -1 and 38 Ω -1 cm -1, respectively, and the conductivity decays slowly with time, indicating that FeCl 3 -doped rare earth poly Acetylene is more stable.Due doping of polyacetylene infrared spectrum at 900cm ~ (-1) and 1400cm ~ (1) at the two doping characteristic peaks doping (y) is less than 0.02 (mole fraction) of the sample cis A narrow peak and a wide peak appeared on the magnetic resonance spectrum. The X-ray diffraction peak of highly doped polyacetylene broadened and flattened. The morphology of the polyacetylene was observed by SEM.
