英文摘要: The synthesis of hierarchically mesoporous polymers with multiple functionalities is challenging. Herein we reported a template-free strategy for synthesis of phenolic azo-polymers with hierarchical porous structures based on diazo-coupling reaction in aqueous solution under mild conditions. The resultant polymers have surface areas up to 593 m(2) g(-1) with the mesopore ratio of > 80%, and a good ability to complex with metal ions, such as Cu2+, Zn2+, Ni2+, achieving a metal loading up to 26.24 wt%. Moreover, the polymers complexed with Zn showed excellent performance for catalyzing the reaction of CO2 with epoxide, affording a TOF of 2570 h(-1) in the presence of tetrabutyl ammonium bromide (7.2 mol%). The polymer complexed with Cu could catalyze the oxidation of alcohol with high efficiency.
