Covalent organic frameworks(COFs)are a class of crystalline porous organic materials linked by strong covalent bonds.1 In 2005,Yaghi and his co-workers demonstrated the utility of the topological design principle in their synthesis of the first successful examples of COFs.2 Cyclotriveratrylene(CTV)is a C3 symmetrical,rigid macrocyclic molecule with a bowl-shaped shallow cavity which can be utilized to construct 3+2 and 3+3 COFs.3 Here we have synthesized a series of aCTV based covalent organic framewoks(COFs),aCTV-COF1 to aCTV-COF7 through dynamic chemistry and their different properties were studied.
