Preparation and Characterization of Spirobisindane Linked Porphyrin Based Polyamide Networks with Intrinsic Microporosity and Catalyst of Knoevenagel Condensation

A new porphyrin based polyamide(PA) network with intrinsic microporosity (PIM-Spiro) is synthesized by the condensation of 3,3,3',3'-tetramethyl 1,1'- spirobisindane(Spiro-DA) and 5,10,15,20-tetra(4-carboxyphenyl) porphyrin(TCPP). PA-PPDA, PA-ODA polyamide networks are also synthesized using p- phenylenediamine(PPDA)、4,4'-oxybisbenzenamine(ODA) as monomers under the same synthesis condition. The microporous structure and physicochemical properties are characterized by FT-IR, SEM, TG and nitrogen adsorption test. Results show that spiro structure of diamine monomer can improve the PA networks BET surface effectively and give the PIM-Spiro excellent swellable property in solvent. The PA networks have high efficiency basic catalytic property owing to the rich N—H covalent of porphyrin group and amide bonds.
