摘要： An emissive semi-interpenetrating polymer network (E-semi-IPN) includes a semi-interpenetrating polymer network and an emissive material interlaced in the polymer network. The semi-interpenetrating polymer network includes in a crosslinked state one or more of a polymerized organic monomer and a polymerized organic oligomer, polymerized water soluble polymerizable agent, and one or more polymerized polyfunctional cross-linking agents. The E-semi-IPN may be employed as an E-semi-IPN layer (16, 36, 56) in organic light emitting devices (10, 20, 30, 40).
