Abstract
A novel thermally stable and semiconducting polyheterocycle, poly(1,3, 4-oxadiazole amine), was synthesized from 2-(p-aminophenyl)-1,3,4-oxad iazolin-5-one via ring-opening. The polymer is a new class of ordered alternating copoly(aniline) containing 1,3,4-oxadiazole heterocyclic u nits. The polymer is highly thermally stable and exhibits no weight lo ss up to 370 degrees 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.
