A chiral, octahedral M L cage, which is charge neutral and contains an internal void of about 2000 Å , is reported. The cage was synthesised as an enantiopure complex by virtue of amino-acid-based dicarboxylate ligands, which assemble around copper paddlewheels at the vertices of the octahedron. The cage persists in solution with retention of the fluorescence properties of the parent acid. The solid-state structure contains large pores both within and between the cages, and displays permanent porosity for the sorption of gases with retention of crystallinity. Initial tests show some enantioselectivity of the cage towards guests in solution.
报道了一种手性八面体M L笼,其呈电中性,内部有一个约2000 Å的空隙。该笼是通过基于氨基酸的二羧酸配体合成的对映体纯配合物,这些配体围绕八面体顶点处的铜桨轮组装。该笼在溶液中保持稳定,并保留了母体酸的荧光特性。固态结构在笼内和笼间均含有大孔,并表现出用于气体吸附的永久孔隙率且保持结晶性。初步测试表明该笼对溶液中的客体具有一定的对映选择性。
