一种荧光气敏材料及其在苯系物传感器上的应用
摘要：
本发明提供了一种荧光气敏材料及其在苯系物传感器上的应用，该荧光气敏材料通过双聚体[PtII(CN-tC4H9)4][PtII(CN)4]在反应温度180-220℃下，加热0.5-2h制得。其中双聚体[PtII(CN-tC4H9)4][PtII(CN)4]由Pt(CH3CN)2Cl2、[(nBu)4N]2[Pt-(CN)4]和叔丁基异腈在乙腈溶剂中搅拌制得；[Pt(CH3CN)2Cl2]由K2[PtCl4]和乙腈在水溶液中室温搅拌制得；[(nBu)4N]2[Pt-(CN)4]由K2Pt(CN)4和四丁基氯化铵在水溶液中室温搅拌，再经萃取分离纯化制备。将所制备的荧光气敏材料应用在苯系物传感器上，荧光仪的激发光经平面镜反射，照射到聚焦透镜上，经聚焦透镜照射到荧光气敏材料薄膜上，再经聚焦透镜被集中照射到荧光仪检测器上进行检测，通过检测荧光气敏材料薄膜吸收苯系物前后荧光强度和位移的变化，测定苯系物气体的种类和浓度。
摘要（英）：

The invention provides a fluorescent gas-sensitive material and application thereof to a benzene series sensor. The fluorescent gas-sensitive material is prepared by heating double polymers [pt(CN-C<4>H<9>)<4>][Pt(CN<4>)] at the reaction temperature of 180 DEG C-220 DEG C for 0.5-2 h, wherein the double polymers [pt(CN-C<4>H<9>)<4>][Pt(CN<4>)] are prepared by stirring Pt(CH<3>CN)<2>Cl<2>, [(Bu]<4>N]<2>[Pt-(CN)<4>] and T-butyl isonitrile in acetonitrile solvents; the Pt(CH<3>CN)<2>Cl<2> is prepared by stirring K<2>[PtCl<4>] and acetonitrile in aqueous solutions at roomtemperature; the [(Bu]<4>N]<2>[Pt-(CN)<4>] is prepared by stirring K<2>Pt(CN)<4> and tetrabutyl ammonium chloride in the aqueous solutions at the room temperature and through the steps of extraction, separation and purification. The prepared fluorescent gas-sensitive material is applied to the benzene series sensor, and exciting light, reflected through a plane mirror, of a fluorometer irradiates to a focusing lens, irradiates to a fluorescent gas-sensitive material film through the focusing lens, and then is centralized and irradiates to a fluorometer detector through the focusing lens fordetection. The types and concentration of benzene series gases are detected through detection of the fluorescence intensity and displacement change of the fluorescent gas-sensitive material film before and after absorbing benzene series.
