H4DTATC = 5,5'-(9,10-dihydroxy-4a,9,9a,10-tetrahydroanthracene-9,10-diyl)diisophthalic acid) was successfully prepared by a hydrothermal method. The structure of HNU-39 comprises UO8 hexagonal bipyramids linked by doubly protonated DTATC ligands, forming a ribbon arrangement. It is worth noting that the DTATC ligand was transformed in situ from 5,5'-(anthracene-9,10-diyl)diisophthalic acid (H4DPATC) during
一种基于铀的金属-有机骨架,[(UO2)(H2DTATC)](HNU-39,H4DTATC = 5,5'-(9,10-二羟基-4a,9,9a,10-四氢蒽-9,10-通过水热法成功地制备了二(二基)二间苯二甲酸)。HNU-39的结构包含UO8六角形双锥体,双锥体质子化的DTATC配体相连,形成带状排列。值得注意的是,在HNU-39合成过程中,DTATC配体是从5,5'-(蒽-9,10-二基)二间苯二甲酸(H4DPATC)原位转化而来的。对荧光性质的研究表明,HNU-39在碱性条件下表现出荧光开启响应,可以用作潜在的pH传感器。此外,HNU-39还可以成功地应用于污水处理厂的实际样品中的pH传感。
