| Popis: | In this study, we succeeded in the crystal surface modification of metal–organic framework (MOF) with an organic polymer by site-specific radical polymerization. A MOF was selected with interpenetrated structure containing a naphthalenediimide moiety with electron accepting capability. N, N-dimethylaniline, as an electron donating guest, induced electron transfer to the napthalenediimide moiety, generating radical anions on the pore and crystal surfaces, initiating radical polymerization. The resulting composite was examined in detail with XRD, TG, TEM, ICP, IR, gas adsorption, and fluorescent measurements, demonstrating that an organic polymer was generated only on the crystal surface, preserving the original porous property. In addition, higher structural stability in response to H2O was observed after polymer wrapping. |
