摘　　要：利用Alder法合成了四苯基卟啉锌配合物并对它进行表征;用匀胶机将一定浓度的四苯基卟啉锌溶液做成薄膜固定在钾离子(K+)交换玻璃光波导表面研制了高灵敏的四苯基卟啉锌薄膜/K+交换玻璃光波导传感器,并对挥发性有机气体进行检测。实验结果表明,在室温下该传感器对低浓度的苯乙烯、二甲苯、甲苯等蒸气具有一定的响应,其中对苯乙烯的响应最大;能够检测到1×10-9(V(苯乙烯)/V(空气))的苯乙烯蒸气,其响应和恢复时间分别为2和7 s。该传感器具有灵敏度高,回复-响应时间快,可逆性等特点。By Alder method zinc tetraphenylporphyrin complex was synthesized and its structure was characterized. Zinc tetraphenylporphyrin film was deposited onto the surface of single mode potassium ion（K＋） exchanged glass optical waveguide（OWG） by spin coater. The OWG sensor was fixed on the gas sensor system to detect volatile organic compound gases. This sensor has can respond towards low concentration of styrene,xylene,and toluene gases at room temperature. Among them styrene gas has the best response. The response and recovery time of styrene gas in 1 × 10- 9（V（Styrene） /V（Air）） volume fraction were 2 s and 7 s,respectively. The sensor has high sensitivity,fast response,recovery speed,and good reversibility.
