[摘要]:Thermal treatment of highly stable porous organic polymers based upon the Yamamoto polymerization of 2,2',7,7'-tetrabromo-9,9'-spirobifluorene was done. The polymers are shown to be thermally and chemically stable. Upon thermal treatment the polymers are shown to have BET surface areas of ca. 2,000 m(2)/g and 2,500 m(2)/g respectively. |
