Rod-like poly-p-phenylene polyelectrolytes bearing four quaternized te
traalkylammonium functionalities per p-phenylene repeating unit are ea
sily available via conversion of poly[2,5-di(6-iodohexyl)-1,4-phenylen
es] with a large excess of TMEDA followed by the quaternization of the
second TMEDA amino group with EtI.
