Two poly(pyridinium salt)s, with tosylate and triflimide as counterions, were prepared by either the ring‐transmutation polymerization of phenylated bis(pyrylium tosylate) salt with 1,9‐diaminononane in DMSO or the metathesis reaction of the corresponding tosylate polymer with lithium triflimide in acetonitrile. They were characterized for both their thermotropic liquid‐crystalline and light‐emitting properties, with various experimental techniques.
