A holey host : An octupolar porous metal–organic framework with a T d ‐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 2 PO 4 . 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.
