A series of uranyl–organic frameworks (UOFs), [(UO2)2(H2TTHA)(H2O)]·4,4′-bipy·2H2O}n (1), [(UO2)3(TTHA)(H2O)3]}n (2), and [(UO2)5(TTHA) (HTTHA)(H2O)3]·H3O}n (3), have been obtained by the hydrothermal reaction of uranyl acetate with a flexible hexapodal ligand (1,3,5-triazine-2,4,6-triamine hexaacetic acid, H6TTHA). These compounds exhibited three distinct 3D self-assembly architectures as a function
一系列的铀酰-有机骨架(UOF),[(UO 2)2(H 2 TTHA)(H 2 O)]·4,4'-bipy·2H 2 O} n(1),[(UO 2)3(TTHA)(H 2 O)3 ]} n(2)和[(UO 2)5(TTHA)(HTTHA)(H 2 O)3 ]·H 3 O} n(3),通过乙酸铀酰与柔性六足配体(1,3,5-三嗪-2,4,6-三胺六乙酸,H 6TTHA)。通过单晶结构分析,这些化合物表现出三种不同的3D自组装体系结构,作为pH的函数,尽管在每个反应中使用的配体都是相同的。出人意料的是,在这项工作中,H 6 TTHA配体的所有配位模式都是首次发现的。此外,光致发光结果表明这些化合物显示出对硝基苯的高灵敏度发光感测功能。另外,表面光电压谱和电场诱导的表面光电压谱表明,化合物1 - 3可以表现为p型半导体。
