研制了一种基于超分子隐吩A的石英晶体微天平（QCM）气体传感器。以香草醇为原料，采用双三聚法合成了超分子隐啡烷-A，并通过电喷雾法将其沉积在QCM装置上。将传感器暴露于各种浓度的CH 4气体和在不同温度下操作的其它气体。还研究了湿度的影响。该传感器对甲烷气体具有选择性，在室温下具有快速的响应和恢复。甲烷的检测限为0.05%（v/v）。初步探讨了CH_4气体与Cryptophane-A相互作用的机理。(C)2009 Elsevier B. V.保留所有权利。
A supramolecular cryptophane-A-based quartz crystal microbalance (QCM) gas sensor has been developed. Supramolecular cryptophane-A was synthesized from vanillyl alcohol using a double trimerisation method and deposited on a QCM device via electrospray method. The sensor was exposed to various concentrations of CH4 gas and other gases operated at different temperatures. The influence of humidity was also examined. The sensor's response showed that it is selective to methane gas, A fast response and recovery was observed at room temperature. Detection limit for methane is 0.05% (v/v). The mechanism of the interactions between CH4 gas and cryptophane-A was discussed preliminarily. (C) 2009 Elsevier B.V. All rights reserved.
