这项工作表明，用于催化二氧化碳固定的多孔固体系统可以通过碳-碳键形成反应直接组装含金属salen的结构单元与有机连接体来开发。为了用作二卤代结构单元，制备具有两个碘基团的Al、Cr、Co-salen结构单元。Sonogashira偶联这些积木与四（4-乙炔基苯基）甲烷导致微孔有机网络（MONs）轴承铝，铬，钴salen物种（Al-MON，Cr-MON，Co-MON）。扫描电子显微镜（SEM）显示，材料具有颗粒或球形形状。Brunauer-Emmett- Teller（BET）分析显示，表面积高达522-650 m（2）g（-1），微孔（
This work shows that porous solid systems for catalytic carbon dioxide fixation can be developed by a direct assembly of metal-salen containing building blocks with organic connectors through a carbon-carbon bond formation reaction. For use as a dihalo building block, Al, Cr, Co-salen building blocks with two iodo groups were prepared. Sonogashira coupling of these building blocks with tetra(4-ethynylphenyl) methane resulted in microporous organic networks (MONs) bearing Al, Cr, and Co-salen species (Al-MON, Cr-MON, Co-MON). Scanning electron microscopy (SEM) showed that the materials had granular or spherical shapes. Brunauer-Emmett- Teller ( BET) analysis revealed surface areas of up to 522-650 m(2) g(-1), and microporosity (
