A Photoluminescent Uranyl Complex for Dual-Platform X-ray Dose Detection
The self-assembly of uranyl cations, oxalic acid, and homopiperazine under melt-assisted reaction conditions resulted in a 0D uranyl molecular complex, UO<sub>2</sub>(HOX)<sub>2</sub>(H<sub>2</sub>O)·HPIP·2H<sub>2</sub>O (<b>U-OX</b>), which includes free water and homopiperazine molecules. This unique complex exhibits significant fluorescence quenching upon UV and X-ray irradiation. The fluorescence quenching is attributed to radiation-induced oxalate free radicals. Moreover, <b>U-OX</b> demonstrates excellent radiolytic and humidity stability, making it a promising dosimeter for X-ray dose detection in harsh environments. Additionally, the dual signals from radiation-induced free radicals and fluorescence quenching enable its use for dual-platform X-ray dose detection.
