合成了一种2,2'-联吡啶功能化的微孔有机聚合MOP-bipy,与Pd(CH3CN)2Cl2络合后得到一种复合材料Pd/MOP-bipy.用碳固体核磁(13C CP/MAS NMR)、傅里叶变换红外光谱(FT-IR)、粉末X射线衍射(PXRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、氮气吸附(nitrogen adsorption)和热重分析(TG)对材料进行表征.用电感耦合高频等离子光谱(ICP)和X射线光电子能谱(XPS)确定了Pd/MOP-bipy材料中Pd的含量和价态.该复合材料在水相催化Suzuki-Miyaura反应和甲醇与水的混合溶剂中催化Sonogashira偶联反应中表现出卓越的催化活性.Pd/MOP-bipy催化剂表现出至少五次循环的重复利用性.

A microporous organic polymer bearing 2, 2'-bipyridine functional group (MOP-bipy), has been synthesized. After treating with Pd (CH3CN)2Cl2, a composite material Pd/MOP-bipy was obtained. The materials have been characterized by 13C CP/MAS NMR, FT-IR, PXRD, SEM, TEM, nitrogen adsorption and thermogravimetric (TG) techniques. The content and valence of palladium in Pd/MOP-bipy have been determined by ICP and XPS. The composite material Pd/MOP-bipy exhibits excellent catalytic activity for Suzuki-Miyaura reaction in water and Sonogashira coupling reaction in methanol/water. The catalyst can be recycled at least five times without significant loss of the activity.
