摘要/Abstract

合成了一种联萘酚（BINOL）功能化的多孔有机聚合物POP-BINOL，用碳固体核磁谱（¹³C CP/MAS NMR）、傅里叶变换红外光谱（FT-IR）、X射线粉末衍射（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）对聚合物材料进行了表征.POP-BINOL经Ti（OⁱPr）₄处理后得到的复合材料可用于非均相催化Et₂Zn对醛的不对称加成反应，得到几乎定量的产率、中等及偏上的ee值，并表现出良好的循环使用性.

A functionalized porous organic polymer POP-BINOL has been prepared and characterized by various techniques including carbon-13 cross-polarization magic-angle spinning nuclear magnetic resonance (¹³C CP/MAS NMR), fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (pXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption and thermogravimetric analysis (TG). After being treated with Ti (OⁱPr)₄, the composite material could be used as highly effective and reusable heterogeneous catalyst for asymmetric diethylzinc addition to aldehydes with medium and upper ee value.
Key words: porous organic polymers, BINOL, heterogeneous catalysis, asymmetric addition reaction
