Three tobacco types (Burley, Flue Cured, and Oriental) and eight cigarette brands were unequivocally identified using an electronic nose formed by only three sensors based on a single novel conducting polymer (PF-BTB) doped with different porphyrins (H2TPP, H2TPFP, and H2BTBOP). The synthesis and characterization of the polymer are also discussed. Small changes in the porphyrin structure caused significant changes in the electrical conductance response patterns of the sensors upon exposure to complex chemical matrixes, representing a novel approach for tuning the selectivity of chemiresistive sensors for e-nose application. This e-nose is fast, cheap, reliable, can be easily operated, and could be a valuable tool for border agents fighting cigarette smuggling around the world, helping them prevent losses of millions in tax revenues and sales.

基于导电聚合物/卟啉复合传感器的电子鼻识别烟草类型和卷烟品牌

三种烟草类型(白肋烟,烤烟,和东方)和8个卷烟品牌使用由只有三个基于单一新颖导电聚合物传感器形成的电子鼻被明确地鉴定(PF-BTB)掺杂有不同的卟啉(ħ 2 TPPħ 2 TPFPH 2 BTBOP)。还讨论了聚合物的合成和表征。卟啉结构的细微变化在暴露于复杂的化学基质时会导致传感器的电导响应模式发生重大变化,这代表了一种用于调节电子鼻应用化学阻滞传感器选择性的新方法。这种电子鼻子快速,便宜,可靠,易于操作,并且对于边境代理打击世界各地的香烟走私,可能是一种宝贵的工具,可帮助他们避免数百万的税收和销售损失。
