## Abstract 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 unit
