Abstract: Disclosed is a coating comprising a polymeric layer, wherein the polymeric layer comprises a reaction product of a first monomer comprising two or more aromatic acetylene groups and a second monomer comprising two or more cyclopentadienone groups, or a cured product of the reaction product. The coating may or may not additionally contain a crosslinker and/or a thermal acid generator. Optical thin films made from the coatings exhibit refractive indices that make them useful as interlayers for matching refractive indices between adjacent layers of display devices; thereby improving device output efficiency.

Abstract: Disclosed is a formulation comprising a copolymer comprising one or more high refractive index first monomers and one or more second monomers comprising a reactive side chain and one or more solvents. The formulation may optionally contain additional components. Further disclosed are methods for forming optical thin films from the formulation and optical devices containing the optical thin films.
