New conjugated light emitting polymers containing benzimidazole moieties wee designed and synthesized. The resulting polymers had high Tg and Td and showed blue photoluminescence and high quantum yields. Their single-layer LED devices emitted blue light. Moreover, the polymers were efficient hosts for triplet dopant Ir(PPY)3.
