The functional N-bearing conjugated microporous polymers (NCMPs) were synthesized by conventional palladium-catalyzed Sonogashira-Hagihara coupling polymerization. The molar ratio of alkyne to halogen functionalities has a significant influence on the thermal stability, morphology and porosity of the resulting polymers. The thermal stability and special surface areas as well as total pore volumes of the resulting polymers was enhanced with the increase of the molar ratio and the surface area reached up to 760 m(2) g(-1). Taking advantages of their amine functionalization and excellent physical and chemical properties, the NCMPs show great potential applications in CO2 storage. This work is expected to provide fundamental guide for the design of novel functional tubular CMPs materials by tuning the molar ratio of arylethynylenes to aryl halides and expanding their applications such as gas storage and separation.
