The synthesis, characterization and CO₂ uptake tendency of a new porous organic polymer (POP) based on porphyrin-pyromellitic dianhyderide is enclosed. The reported porphyrin POP was achieved by exploiting the condensation reaction between tetraaminophenylporphyrin (TAPP) with benzenetetracarboxylic (pyromellitic) diahhydride in dry dimethylforamide (DMF). The structure of the resulting polymer was confirmed by FT-IR as well as solid state ¹³C cross-polarization magic angle spinning (CP/MAS) NMR studies. In addition, the post-synthetic metallation of the free-base porphyrin macrocycles of the resulting POP with either Zn or Mn metals afforded the metallo-porphyrin POP analogues in excellent yields. The morphology of the reported porphyrin POPs were investigated by scanning electron microscopy (SEM) which demonstrated the porosity of the resulting POPs. Furthermore, CO₂ adsorption capabilities of the synthesized POPs were evaluated and Brunauer-Emmett-Teller (BET) surface area was found to be 542, 597 and 828 m²/g for free-base, Zn- and Mn^III-POP, respectively. Finally, Mn^III-POP was found to be an effective catalyst for the selective epoxidation of styrene to the corresponding epoxide.

封闭了一种新型的基于卟啉-均苯四酸二酐的多孔有机聚合物（POP）的合成，表征和CO ₂吸收趋势。通过利用四氨基苯基卟啉（TAPP）与苯四甲酸（均苯四甲酸）二酐在干燥的二甲基甲酰胺（DMF）之间的缩合反应来实现所报道的卟啉POP。傅立叶变换红外光谱（FT-IR）和固态¹³证实了所得聚合物的结构C交叉极化魔角旋转（CP / MAS）NMR研究。另外，所得的POP与锌或Mn金属的游离碱卟啉大环的合成后金属化以优异的产率提供了金属卟啉POP类似物。通过扫描电子显微镜（SEM）研究了所报道的卟啉POPs的形态，证明了所得POPs的孔隙率。此外，评估了合成POPs的CO ₂吸附能力，发现Brunauer-Emmett-Teller（BET）表面积对于游离碱，Zn-和Mn ^III -POP分别为542、597和828 m ² / g。。最后，Mn ^III发现-POP是将苯乙烯选择性环氧化为相应的环氧化物的有效催化剂。
