摘　　要：锌卟啉和锌酞菁可以模拟人类嗅觉细胞。介绍了用四苯基卟啉锌,八乙基卟啉锌和锌酞菁作为气味敏感材料的可视嗅觉敏感阵列的制作方法,并用制成的阵列在自行设计的可视嗅觉电子鼻系统中对六种有机胺进行了识别实验。对实验的数字图像响应信息分别在色度空间和光度空间进行了分析与表达,结果表明,所设计的可视嗅觉电子鼻系统对六种分析物的响应模式是彼此特异的,能够在两分钟内识别各分析物,而且可以分辨分析物分子结构的类属差异。Znic porphyrins and zinc phthalocyanines may mimic human olfactory receptors well. The paper presented a method of developing smell-seeing sensitive arrays by using Zn（ Ⅱ ）TPP, Zn（ Ⅱ）OEP and Zn （ iI ）Pc as odour sensitive materials. The arrays were then equipped in a self-designed smell-seeing electronic nose system to recognize six organic amines. The testing digital image response data was analyzed and shown in color space and spectral space respectively. The results showed that the response patterns of the smell-seeing electronic nose upon the six amines were highly special to each other and those analytes with similar molecular structures were clustered together. All the recognitions could be achieved in two minutes.
