摘要:
Cross-linkable hole transport polymers comprising at least one first monomer comprised of an arylamine and at least one second monomer comprised of a fluorene, carbazole, diphenylsilicon or fused heterocyclic derivative are provided. In some embodiments, the hole transport polymers also comprise at least one third monomer, different from the second monomer, and comprised of a fluorene, carbazole, diphenylsilicon or fused heterocyclic derivative. Electronic devices made with the polymeric materials are also provided.
