我们报告了基于溶液处理的有机场效应晶体管(OFET)的化学传感器，用于检测挥发性有机化合物(VOCs)。这些场效应管是在柔性塑料衬底上制备的，工作在低电压(≤3-V)下，具有高性能。这些OFET可用于检测一系列VOCs，包括醇和酮。这些装置的灵敏度取决于分析物的极性，具有较长烷基链的疏水分析物比具有较短烷基链的疏水分析物显示出更高的灵敏度。这些设备的阵列适用于便携式传感器应用，如环境监测、食品质量监测和医疗诊断。
We report chemical sensors based on solution processed organic field-effect transistors (OFETs) for detecting volatile organic compounds (VOCs). The OFETs were prepared on flexible plastic substrates and operated at low voltages (≤3 V) with high performance. These OFETs can be used to detect a range of VOCs, including alcohols and ketones. The sensitivity of these devices depends on the polarity of the analytes, and more hydrophobic analytes with longer alkyl chains show higher sensitivities than those with shorter alkyl chains. Arrays of these devices are suitable for portable sensor applications, such as environmental monitoring, food quality monitoring, and medical diagnostics.
