Abstract
The invention discloses a block copolymer intrinsic stretchable electroluminescent elastomer and its preparation method and application. This type of elastomer is made from organic electroluminescent monomers, styrene and 1,3-butadiene through anionic polymerization. The innovation of the present invention is: for the first time, the organic electroluminescence unit is introduced into the elastomer by chemical crosslinking. On the basis of improving the intrinsic stretchability of the elastomer, at the same time, it has characteristics of excellent luminescence and high carrier mobility, novel structure and unique design strategy; meanwhile, it also solves the inherent non-stretchability problem of traditional organic optoelectronic materials and the problem that traditional elastomers do not have electroluminescent properties. This type of elastomer is used as a light-emitting layer material to prepare organic electroluminescent devices with high stability, high stretchability and high efficiency.
