Abstract: The present invention comprises diamantane groups interspersed among benzothiazole groups, benzoxazole groups or benzimidazole groups. This constitutes a rigid-rod polymer with stable cycloaliphatic groups interspersed into the aromatic-heteroaromatic backbone of the rods. The presence of the aliphatic groups decreases crystallinity by adding disorder to the rods thus minimizing interactions between the heteroaromatic groups. The interspersed aliphatic groups act as insulators and thus permit greater relative protonation. Also, the reduced conjugation of the aromatic-heteroaromatic rings reduces the color of the polymers. The preferred method of manufacturing this improved rigid-rod polymer is by condensation of dimethyl diamantanecarboxylate with 2,5-diamino-1,4-benzenedithiol, 1,2,4,5-tetraaminobenzene, or 4,6-diamino-1,3-benzenediol.
