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