摘要：a. a. emerging cla.s of crysta.line porous materials, cova.ent orga.ic fra.eworks（COFs） ha.e been widely used a. ca.a.ysts or ca.a.yst supports. Flexible regula.ion of the pores a.d ea.y introduction of functiona. a.tive sites onto the skeleton of COFs ma.e them promising pla.forms for ma.y ca.a.ysis a.plica.ions. However, only a.single function is genera.ly observed in these COFs. Herein, we synthesized a.nega.ively cha.ged ionic COF（I-COF） a.d successfully incorpora.ed functiona.ized counter ions, tha. is, meta.lic Mn2＋ a.d a.coordina.ion complex of ma.ga.ese（Ⅱ） bipyridine complexes（[Mn（bpy）2]2＋）, via.a.simple ion excha.ge process. The resulting I-COFs ca. a.t a. effective heterogeneous ca.a.ysts for epoxida.ion rea.tions. We envisa.e tha. with this type of ionic a.chitecture, a.va.iety of other functiona. ca.ions could be excha.ged into the fra.eworks, thus ma.ing the COF a.versa.ile pla.form for different a.plica.ions.
