Abstract

Picoline amide-based calix[4]arene molecule was the first time deposited onto gold substrate as an active layer by using Langmuir-Blodgett (LB) coating technique. UV-visible, atomic force microscopy, and surface plasmon resonance (SPR) technique were used to control monolayer quality. The sensing properties were investigated by exposing the LB thin film to different percentage of organic VOCs vapors such as acetone, benzene, chloroform, ethyl acetate, and methanol in air-VOCs mixture. SPR results showed that this calix[4]arene molecule is a good candidate with a fast and reversible sensor response for VOCs sensing applications.

摘要

通过使用Langmuir-Blodgett（LB）涂层技术，首次将基于吡啶甲酚酰胺的杯芳烃[4]芳烃分子作为活性层沉积到金基底上。紫外可见光，原子力显微镜和表面等离振子共振（SPR）技术用于控制单层质量。通过将LB薄膜暴露于空气-VOCs混合物中的不同百分比的有机VOC蒸气（例如丙酮，苯，氯仿，乙酸乙酯和甲醇）中，研究了传感特性。SPR结果表明，此杯芳烃[4]芳烃分子对于VOC传感应用具有快速且可逆的传感器响应，是一个不错的选择。
