在本文中，我们报道了含Cu和Zn金属（CuPc和ZnPc）的含3个氧联酞菁的s-三嗪薄膜的表征和有机气敏性能。室温下CuPc和ZriPc单层膜的单分子表面压力面积（pi-A）等温线表明，两种材料在空气-水界面处形成了稳定的单层膜。利用紫外可见光谱和石英晶体微天平对CuPc和ZnPc材料的LB膜沉积过程进行了表征。结果表明，在传递比大于0.95的情况下，可以制备出高质量、均匀的LB膜，并且所制备的LB膜对氯仿的敏感性明显高于其他气体。LB薄膜的响应速度快、强度大、可逆。这些新合成的CuPc和ZnPc材料在氯仿蒸汽的室温挥发性有机气敏装置的开发中是有前途的传感材料。(C) 2006 Elsevier B.V.版权所有
In the present article, we report about the characterisation and organic vapour sensing properties of Langmuir-Blodgett thin films of s-triazines bearing three oxygen-linked phthalocyanines incorporating Cu and Zn metals (CuPc and ZnPc). Surface pressure-area per molecule (pi-A) isotherms of CuPc and ZriPc monolayers at room temperature shows that stable monolayers of both materials are formed at the air-water interface. The LB film deposition processes of CuPc and ZnPc materials are characterized by UV-vis spectroscopy and a quartz crystal microbalance. The results indicate that high quality and uniform LB films can be prepared with the transfer ratio of over 0.95 and that the obtained LB films are significantly more sensitive to chloroform than other vapours. The response of the LB films is fast, large, and reversible. These newly synthesised CuPc and ZnPc materials are promising sensing materials in the development of room temperature volatile organic vapour sensing devices for chloroform vapour.
