A novel thermally stable and semiconducting polyheterocycle, poly(1,3,4‐oxadiazole amine), was synthesized from 2‐( p ‐aminophenyl)‐1,3,4‐oxadiazolin‐5‐one via ring‐opening. The polymer is a new class of ordered alternating copoly(aniline) containing 1,3,4‐oxadiazole heterocyclic units. The polymer is highly thermally stable and exhibits no weight loss up to 370°C in air. Its electric conductivity is less than 10 −10 S · cm −1 at ambient temperature, but markedly increases to 6,5 · 10 −7 S · cm −1 upon doping with iodine.
