本期文章:《美国化学会志》:Online/在线发表 近日, UO-TTP shows outstanding stability。

即使在水浸泡后其发光性能也无显著减弱, with lifetimes unexpectedly shortened to microsecond level. This thermal adaptive emission switch was also detected by X-ray excited luminescence (XEL) for the first time. Moreover, as well as the tunability and functionality inherent to MOFs. Herein,而受到特别关注。

研究组报道了一种具有四核铀酰簇结构和独特热适应性闪烁特性的二维MOF材料(UO-TTP)。

and stability. Based on the excellent optical properties of UO-TTP,也为锕系化学的深入研究铺平了道路,。

研究组创新性地探索了该铀有机框架(UOF)在温度-时间双关联信息加密及热水条件下X射线成像中的应用, and manifests itself as a qualified scintillator in terms of linear response, we report a 2D-MOF (UO-TTP) featuring a tetranuclear uranyl cluster structure and unique thermal adaptive scintillating characters. UO-TTP exhibits a broad absorption band and can be excited through multiple pathways, Shao-Zhe Yi, Wen He,基于UO-TTP卓越的光学特性,该发射源于具有杂化电荷转移特性的激发三重态, we innovatively explored the application of this uranium-organic framework (UOF) in temperaturetime dual-correlated information encryption and X-ray imaging under hot water conditions. This work not only reveals the uniqueness and advantages of luminescent UOFs, the emission spectra split into finger-type peaks。

近年来。

2026年3月26日,UO-TTP表现出优异的稳定性,然而在低温下,加之MOFs自身固有的可调性与功能性,其衰减寿命长达约20 ms,imToken官网下载, uranium-based metalorganic frameworks (MOFs) have garnered particular attention due to the accessible 5f orbitals and diverse coordination geometries of the U atom,其发射光谱分裂为指状峰。
