Imine-Linked Microporous Polymer Organic Frameworks

Imine-linked microporous polymer organic frameworks (POFs) were synthesized via Schiff base condensation between 1,3,5-triformylbenzene and several readily available diamine monomers. Our facile, one-pot approach results in quantitative yields of POFs with the flexibility to incorporate several functional groups in their pores for tuning the interaction of their surface with different guest molecules. Synthesized POFs exhibit high specific surface areas (up to 1500 m(2) g(-1)) as well as high isosteric heats of H(2) adsorption (up to 8.2 kJ mol(-1)).
