• Zinc sensor
• H2PO4- sensor
• Highly selective
• Relay recognition
• Ratiometric

A novel fluorescent sensor (AQTF1) based on the N-(quinolin-8-yl) tetrahydrofuran-2-carboxamide was designed and synthesized. This new sensor demonstrated high selectivity for the Zn2+ without the interference from Cd2+. The detection limit of this probe was calculated to be 10.8 nM for Zn2+. The in situ prepared AQTF1-Zn2+ complex was used for detection of H2PO4- and displayed good selectivity from the common anions. Furthermore, the AQTF1 displayed good ratiometric response for the relay recognition for Zn2+ and H2PO4-.
