A series of phenylene based polyelectrolytes were synthesized form biphenyl, 2,2’-biphenol and isatin by superacid catalyzed polyhydroxyalkylation reaction |
| 초록 |
These polymers have all carbon-carbon structure on polymer backbone without ether linkage. Particularly, the poly sulfonyl imide groups were attached to a 2,2’-biphenol unit. Block copolymers offer unique avenues for the structural control of channel which afforded better stability due to less reactive toward nucleophilic substitution reaction, and good proton mobility because of well phase separation. And these synthesized polymers were block copolymer because clear microphase separation observed in the block copolymer membranes Fluorosulfonylimideisocyanate structures were synthesized form isocyanate. Fluorosulfonylimideisocyanate have high pKa more than sulfuric acid. That’s why we expect such types of membranes will show good proton conductivity. The structural properties of the synthesized polymers will investigate by 1H NMR spectroscopy. |
