我们采用化学取代的策略,设计了一种具有大光学各向异性的磷酸盐阴离子结构。具体地说,我们用两个Cl-取代了Ba_3P_3O_(10)Cl中的一个O_2-,从而形成了一个新的化合物BaPO_3Cl(P_21/ c)。值得注意的是,这种化合物是第一种具有无限[PO 3]∞链的金属磷酸盐氯化物,它显示出良好的化学和热稳定性,以及短的UV截止边缘(<200 nm)和相对较大的双折射。
We adopted a chemical substitution strategy to design a particular anionic structure with large optical anisotropy in phosphate. Specifically, we replaced one O2- in Ba3P3O10Cl by two Cl-, leading to the formation of a new compound of BaPO3Cl ( P21/ c). Notably, this compound is the first metal phosphate chloride featuring infinite [PO3]∞ chains, and it displays good chemical and thermal stability, as well as a short UV cutoff edge (<200 nm) and relatively large birefringence.
