A Germanate Framework Containing 24-Ring Channels,Ni-Ge Bonds,and Chiral [Ni@Ge_(14)O_(24)(OH)_3] Cluster Motifs Transferred from Chiral Metal Complexes

摘要

Microporous materials have been extensively studied due to their widespread applications in ion exchange,separation,and catalysis.Since the discovery of the first aluminum phosphates (AlPOs) VPI-5 with 18-membered rings (18-MR) in 1988,some porous materials with larger rings,such as JDF-20 (20-MR),cloverite (20-MR),VSB-1 (24-MR),ND-1 (24-MR),VSB-5 (24-MR),NTHU-1 (24-MR),FDU-4 (24-MR),ASU-16 (24-MR),and SU-12 (24-MR),have been made.
