新型亚磷酸铀的合成与表征

由于无机微孔晶体具有规则的孔道结构和丰富的结构类型,在吸附、分离、催化、主客体化学等领域的广泛应用,具有新颖结构的微孔晶体的合成一直备受关注。近年来,以假四面体的HPO3基团取代的四面体PO4基团构筑微孔晶体在超大孔微孔晶体的合成领域取得很多成果。ZZ-1的化学式为C10H24N2](UO2)2(HPO3)3].H2O,是以佛尔酮二胺为模板剂合成出的层状亚磷酸铀,其结构是由UO7五双角锥和HPO3假四面体连接形成的4,8元环的网络片层,这些片层的堆积形成了层状结构。层与层之间的嵌有顺式的异佛尔酮二胺阳离子和水分子。ZZ-1在266nm激光激发下发出强烈的绿光。

Synthesis and Characterization of A Novelty Uranium Phosphites

Synthesis of microporous crystals attracted more attention due to their regular tunnel structures and struc- tural versitilities with wide applications in adsorption, seperation, catalysis and host -guest chemistry. Recently, fruitful results were got in the synthesis of microporous crystals with extra - large pores by using pseudo - tetrahedral HPO3 repla- cing conventional tetrahedral PO4 to construct the microporous structures. ZZ - 1 with formula C10H124N2]（UO2）：（HPO3）3]·H2O was a layered uranium phosphite that was synthesized by using isophonodiamine as the template. The structure containing a sheet of 4,8 - network that formed by the connections of U07 pentagonal bypyramid and HPO3 groups. Stacking of the sheets generated the layered structure With diprotonated cis -isophonodiamine cations and water molecules intercalated in the interlayer spaces. Fluorescent spectroscopy analysis revealed that a intense green light emission was observed when ZZ - 1 was excited by 266nm laser.
