专利号:US-7615300-B2 优先权日:2005-08-30 标 题 :Development of novel proton-conductive polymers for proton exchange membrane fuel cell (PEMFC) technology 发明人:BAE CHULSUNG 权利人:REGENTS UNIVERSITY AND COMMUNI 摘要:New thermally and chemically stable sulfonic acid-containing polymers are synthesized via post-sulfonation of aromatic polymers. These new polymers provide unique benefits to proton exchange membrane fuel cell technology (“PEMFCâ€?). As a sulfonic acid moiety can be easily installed into an aromatic ring via electrophilic sulfonation, even in the presence of an electron-withdrawing substituent such as —F, rigid polymers consisting of aromatic rings at either the side chain or main chain can be prepared with a wide range of substituents and flexibility in properties. Novel synthetic procedures are provided for synthesis of the polymers.

Such polymers may serve in the fabrication of novel optoelectronic devices and in the development of highly efficient biosensors. The invention further relates to the application of these polymers in assay methods.
