In the last few years, microporous organic polymers (MOPs) have been the hot field in porous material research for their unquie features including high specific surface area, low skeleton density, high thermal and chemical stability[1].With these advantages, MOPs with abundant accessible catalytic sites, that can be used as unique platform media and functionalized catalyst for organic reactions[2]. Herein, we report a new Triptycene-Derived Imine-Linked Polymer(TP-IM), synthesized via schiff base condensation between 2,6,14-Triaminotriptycene and isophthalaldehyde. It was further used to support palladium nanoparticles (Pd NPs). Image of transmission electron microscopy indicated small-sized Pd NPs well dispersed in the polymer. This polymer-supported Pd material (Pd/TP-IM) was applied as catalyst in Suzuki-Miyaura coupling reaction between a series of arylboronic acid and aryl halides(Figure 1).Moreover,Pd/TP-IM can be reused for five times without loss of product yields. Catalytic transformations of CO2 have gained considerable attention due to its main contribution to global warming. We report a new hydroxyl-functionalized microporosity organic polymer (HF-MOP) which was proved to be a highly efficient heterogeneous catalyst towards the cycloaddition of CO2 and epoixdes (Figure 2). HF-MOP can be easily prepared through condensation reaction of 2,3-dihydroxyterephthalaldehyde and 2,6,14-tranimotriptycene. Its high surface area, together with abundant and uniformly-distributed hydroxyl active sites in the network plays an important role in this cycloaddition. The corresponding cyclic carbonate products were obtained in high to excellent yields under mild reaction conditions.
