摘要

在熔融辅助反应条件下，铀酰阳离子、草酸和同哌嗪自组装生成了0D铀酰分子络合物UO2(HOX)2（H2O）·HPIP·2H2O (U-OX)，其中包括游离水和同哌嗪分子。这种独特的复合物在紫外线和x射线照射下表现出显著的荧光猝灭。荧光猝灭归因于辐射诱导的草酸自由基。此外，U-OX具有出色的辐射分解和湿度稳定性，使其成为在恶劣环境中进行x射线剂量检测的有前途的剂量计。此外，辐射诱导自由基和荧光猝灭的双重信号使其能够用于双平台x射线剂量检测。

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, 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.
