Porphyrin based polyimide PPBPIs(PPBPI-PA、PPBPI-PEPA and PPBPI-PENA)

Crosslinked porphyrin based polyimide (PPBPI-PA-CR、PPBPI-PEPA-CR、PPBPI-PENA-CR)

In this chapter, the pore parameters and CO2 Adsorption and selectivity . secondly , Ellipsoidal structure of hyperbranched polyimide , It is beneficial to introduce the end capping group to modify it . The spatial configuration of the capped monomer ( Conjugation effect and molecular size ) It plays an important role in optimizing hole parameters , On this basis , We introduce three kinds of alkynyl terminated monoanhydrides with different spatial configurations , Three crosslinked porphyrin based polyimides were prepared (PPBPI-PA-CR、PPBPI-PEPA-CR、PPBPI-PENA-CR). suffer π Stacking effect and molecular size effect , With the increase of conjugation effect and molecular size of capped monoanhydrides , The specific surface area of the uncrosslinked polymer decreases (106.8-8.3 m2 g-1), The specific surface area of the crosslinked polymer increases (1.8-633 m2 g-1). And crosslinked polymers have considerable CO2 Adsorption capacity (1.37、2.01、2.37 mmol g-1)、CO2 Endothermic enthalpy (34.8、27.5、22.6 k J/mol) and CO2/N2(39.83、36.95、40.08) And CO2/CH4(14.13、9.78、10.87) Adsorption selectivity . The appropriate spatial configuration of capped monoanhydrides is an important factor affecting the pore parameters of crosslinked polymers . Again , The different spatial positions of alkynyl groups in the polyimide backbone , It will cause the difference of alkynyl crosslinking sites in the polymer chain .
