文摘

A novel two-dimensional molecular space (layered carboxylpropylamidephenylsilica, CPAPhS) with regular carboxylgroups was successfully synthesized through grafting carboxyl groups in the structure of layered (aminophenyl)silicausing butanedioic anhydride. The carboxyl groups regularly arranged in the layered CPAPhS can react with variousorganic molecules with amino and hydroxyl groups through formation of reactive intermediate with catalyzers, suchas SOCl₂. In this research, an example was used to prove the reaction properties of regular carboxyl groups in layeredCPAPhS. The layered CPAPhS was reacted with SOCl₂ to form layered acyl chloridepropylamidephenylsilica (ACPAPhS)and then reacted with n-butylamine and n-butyl alcohol to form layered n-butylamidepropylamidephenylsilica (BAPAPhS)and n-butylesterpropylamidephenylsilica (BEPAPhS) with regular molecular structures. Layered CPAPhS showed thepotential as a starting material for formation of a series of novel two-dimensional molecular space with various regularmolecular structures, and as a solid acceptor for chemical reagent with amino and hydroxyl groups for chemicalprocesses.
