Abstract Palladium(II) ions (Pd 2+ ) are crucial in various fields, including catalysis, medicine, electronics, hydrogen storage, sensors, and imaging. However, their uncontrolled use can lead to toxicity environmental hazards. Therefore, developing selective sensitive Pd sensing probes is vital for ecological safety, biomedical monitoring, sustainable resource management. Herein, we report the synthesis of novel pyrazolopyrido[2,3‐ h ]quinazoline‐based ( PQMe PQCl detection among metal ions. An environmentally benign multicomponent cascade strategy was employed synthesize these hybrid heterocycles. The limits were determined be 0.55 µM 0.71 µM, respectively. binding interaction between confirmed through 1 H NMR titration experiments. Furthermore, fluorescence lifetime measurements supported quenching mechanism upon binding. applicability real‐world analysis evaluated by detecting water samples. Additionally, demonstrated potential fabricated into test strips or swabs efficient on‐site
