A novel carborane-containing compound with ethynyl groups, 1,2-bis[4-(4'-ethynylphenoxy)phenyl]-o-carborane, was synthesized. Cross-linking with 4-iodo- and 4,4'-diiododiphenyl ethers catalyzed by Pd complexes afforded the model bis-arylene ethynylenes and the corresponding polymers. The introduction of a carborane nucleus into the structure of the model compounds and polymers was shown to render these systems soluble.
