摘要：
(Figure Presented) A holey host: An octupolar porous metal-organic framework with a Td-symmetric supercage structure (see picture; green: center of the octapolar structure) exhibits a powder second harmonic generation (SHG) intensity about 15 times higher than that of KH 2PO4. This anionic open framework is highly thermally stable, displays high ion-exchange capacities with the cations NH 4+, Na+, and K+, and, more importantly, exhibits an unprecedented cation-dependent NLO activity. © 2007 Wiley-VCH Verlag GmbH & Co.
