在纯手性开放骨架[Ni-2（L-asp）（2）（bipy）]中用扩展的bipy型配体取代柱撑配体，得到一族层状结构的纯手性金属有机骨架。1D通道拓扑结构可以通过有机连接体的性质进行修饰，具有可调节的形状、横截面和化学官能度。此外，与母体[Ni-2（L-asp）（2）（bipy）]相比，这些通道的体积可以增加高达36%。连接基1，4-二吡啶基苯（3rbp）提供了进入具有不同形状的通道的新的层状纯手性框架[Ni-2（L-asp）（2）（3rbp）]的途径。在特定情况下，具有也作为客体存在的连接体的无孔类似物可以在升华后活化以得到多孔材料。它们的CO2吸收显示相对于母体[Ni，（L-asp）（2）（bipy）]骨架增加高达30%。
Substitution of the pillaring ligand in the homochiral open-framework [Ni-2(L-asp)(2)(bipy)] by extended bipy-type ligands leads to a family of layer-structured, homochiral metal-organic frameworks. The 1D channel topology can be modified by the nature of the organic linker, with shape, cross-section and the chemical functionality tuneable. In addition, the volume of these channels can be increased by up to 36% compared to the parent [Ni-2(L-asp)(2)(bipy)]. The linker 1,4-dipyridylbenzene (3rbp) gives access to a new layered homochiral framework [Ni-2(L-asp)(2)(3rbp)] with channels of a different shape. In specific cases, non-porous analogues with the linker also present as a guest can be activated to give porous materials after sublimation. Their CO2 uptake shows an increase of up to 30% with respect to the parent [Ni,(L-asp)(2)(bipy)] framework.
