Abstract: Organic field-effect transistors (OFETs) are electronic devices showing switching characteristics by applying voltages. Owing to their beneficial device properties, OFETs functionalized with appropriate molecular recognition materials contribute to sensitive detection over conventional electrochemical and optical sensing methods. Real samples, including body fluids, food and drink samples, and environmental water, contain various analytes with different molecular geometries, sizes, and charges. Therefore, the optimal design of recognition sites depending on analytes is required to achieve accurate chemical sensing. For example, the author has developed OFET-based chemical sensors functionalized with molecularly imprinted polymers, allowing selective detection owing to three-dimensional recognition networks against specific analytes. As a further attempt, the author has proposed pattern recognition-driven chemical sensing platforms based on cross-reactive supramolecular receptors. This presentation will discuss the design strategy of artificial recognition materials depending on analytes, and the applicability of the OFET-based chemical sensors functionalized with artificial recognition materials to real-sample analysis.
