Crystalline electrolytes in the system of calixarenesulfonic acids and low molecular weight acids were synthesized and the features of their structure and parameters of proton transfer were studied in a wide range of relative humidity (RH = 20–75%) and temperature (+50 to –80°C). It was shown that the introduction of acids into a nanosized calixarene bowl leads to the formation of supramolecular complexes of three types. The structural features of the materials obtained affect the electrical transport properties of such systems. The highest proton conductivity, reaching 0.08 S/cm at RH = 75% and 25°C, have complexes that are close in structure to the initial calixarenesulfonic acid.

基于杯芳烃和低分子酸的替代质子传导材料,用于低温燃料电池和传感器

合成了杯芳烃磺酸和低分子量酸体系中的结晶电解质,并在较宽的相对湿度(RH = 20–75%)和温度(+50至– 80°C)。结果表明,将酸引入纳米杯芳烃碗中会导致形成三种类型的超分子复合物。获得的材料的结构特征影响这种系统的电传输性能。最高的质子传导率在RH = 75%和25°C时达到0.08 S / cm ,其配合物的结构与初始杯芳烃磺酸接近。
