Zeolite type structures with large cages interconnected by multidimensional 12-ring (rings of 12 tetrahedrally coordinated atoms) channels have been synthesized; more than a dozen large-pore materials were created in three different topologies with aluminum (or gallium), cobalt (or manganese, magnesium, or zinc), and phosphorus at the tetrahedral coordination sites. Tetragonal UCSB-8 has an unusually large cage built from 64 tetrahedral atoms and connected by an orthogonal channel system with 12-ring apertures in two dimensions and 8-ring apertures in the third. Rhombohedral UCSB-10 and hexagonal UCSB-6 are structurally related to faujasite and its hexagonal polymorph, respectively, and have large cages connected by 12-ring channels in all three dimensions.
已合成出具有由多维12元环(12个四面体配位原子环)通道相互连接的大笼子的沸石型结构;在三种不同拓扑结构中制备了十几种大孔材料,其四面体配位位点含有铝(或镓)、钴(或锰、镁或锌)和磷。四方晶系的UCSB - 8具有由64个四面体原子构成的异常大的笼子,并通过一个正交通道系统相连,该通道系统在二维有12元环孔口,在三维有8元环孔口。菱面体晶系的UCSB - 10和六方晶系的UCSB - 6分别在结构上与八面沸石及其六方多晶型物相关,并且在所有三个维度上都有由12元环通道连接的大笼子。
