制备了氧化石墨同基于2,2′-联咪唑(简记为H2biim)和磷钨酸的有机-无机络合物(其分子式简记为{H6[(H2O)1.5(H2biim)2(CH3OH)]2[(H2biim)(CH3OH)2][PW12O40]2·2CH3CN}n(1))的两个复合物(分别简记为1-GO1和1-GO2).利用红外光谱仪和X射线衍射仪表征了合成产物的结构.此外,在25~100℃温度范围内和35%~98%相对湿度范围内,利用电化学阻抗谱测定了2种产物的质子导电性.结果表明,化合物1的结构特征在两个复合物中得以保留.在约98%相对湿度下,1-GO1和1-GO2在温度25~100℃范围内的质子导电率达1.26×10-3~2.2×10-3S·cm-1;在温度100℃、相对湿度35%~98%范围内,1-GO1和1-GO2的质子导电率达0.64×10-3~2.2×10-3S·cm-1.此外,在同等条件下,1-GO1和1-GO2的质子导电性优于化合物1.
