以4-(1H-吡咯基)苯甲酸阴离子为层间阴离子，采用共沉淀法，在恒定pH条件下，经72h水热处理，制备了层状双氢氧化物(层状双氢氧化物)。用X射线衍射仪、~(13)C CP-MAS核磁共振仪、电子自旋共振谱、热重分析和透射电子显微镜对材料进行了表征。X-射线衍射法测得的层间距与插层阴离子双分子层的形成相吻合。固体~(13)C核磁共振和ESR数据有力地表明，在共沉淀过程中，4-(1H-吡咯基)苯甲酸阴离子发生了部分原位聚合。
The two-dimensional hybrid organic–inorganic materials Zn2–Cr and Zn2–Al-LDHs (Layered Double Hydroxides) containing 4-(1H-pyrrol-1yl)benzoate anions as the interlayer anions were synthesized by the co-precipitation method at constant pH followed by subsequent hydrothermal treatment for 72h. The materials were characterized by PXRD,13C CP-MAS NMR, ESR, TGA, and TEM. The basal spacing found by the X-ray diffraction technique is coincident with the formation of bilayers of the intercalated anions. Solid-state13C NMR and ESR data strongly suggest the partial in situ polymerization of the 4-(1H-pyrrol-1yl)benzoate anions during coprecipitation.
