Abstract

Porous polymers were prepared by cyclotrimerization reaction in molten p-toluenesulfonic acid. Their properties could be tailored by functionalization of the aromatic diacetyl monomers. Thus, a range of homo- and copolymers based on hydrogen-, amine-, or nitro-functionalized 4,4′-diacetylbiphenyl derivatives and 1,4-diacetylbenzene was synthesized. The pores size could be tuned from mainly microporous to hierarchical micro- and mesoporous or even hierarchical micro- and macroporous. BET surface areas up to 720 m2/g and total pore volumes up to 1.76 cm3/g were achieved. The formation of different pore types was related to the solvent-monomer/polymer interactions, which is shown by 15N solid state MAS NMR spectroscopy and SEM. Other physical properties such as surface polarity and thermal stability were influenced by the different monomers as well. © 2014 American Chemical Society.
