dynamically modulating electronic properties was applied for the first time towards actinide‐based heterometallic MOFs through integration of photochromic linkers. Optical cycling, modeling of density of states near the Fermi edge, conductivity measurements, and photoisomerization kinetics were employed to shed light on the process of tailoring optoelectronic properties of An‐MOFs. Furthermore, the first
获得基于act系元素的材料的属性的基础知识是创造新的可能性的必要步骤,以应对当前在核能和核废料领域的挑战。在本报告中,我们首次建立了含act系元素的金属有机骨架(An-MOF)与激发波长的函数的光物理-电子相关性。通过集成光致变色连接体,首次对基于act系元素的异金属MOF首次采用了动态调节电子特性的逐步方法。使用光学循环,费米边缘附近的状态密度建模,电导率测量和光异构化动力学来阐明An-MOF的光电特性定制过程。此外,构造了第一个基于光致变色MOF的场效应晶体管,其中可以通过曝光来改变场效应响应。作为演示,曝光后的电流变化足以操作两个LED故障安全指示器电路。
