Abstract
The self-assembly of uranyl cations, oxalic acid, and homopiperazine under melt-assisted reaction conditions resulted in a 0D uranyl molecular complex, UO2(HOX)2(H2O)·HPIP·2H2O (U-OX), 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, U-OX 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.
