A new rim-differentiated pillar[5]arene (RD-P5) has been synthesized and immobilized onto an Al 2 O 3 surface for the rapid detection of perfluoroalkyl acids. This P5-Al 2 O 3 surface provides a novel approach for measuring perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) using contact angle measurements, with limits of detection down to 10 ng L -1 .
