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.
