Abstract: The present disclosure discloses a manufacturing method for a high-resolution array organic film, and use thereof The high-resolution array organic film manufacturing method performs, by means of electrochemical deposition, polymerization of electrically active monomers on a high-resolution display screen array substrate to deposit and form a high-resolution array organic film. Also disclosed is a use of the manufactured high-resolution array organic film in manufacturing of OLED display screens. By employing electrochemical deposition to deposit the high-resolution array film on the high-resolution array substrate, the present disclosure provides a high-resolution film forming technique having simple operation, a low cost, film controllability, and precision up to 10 ?M.

Abstract: The invention relates to optical devices comprising a substrate and at least one semiconductive polymer supported by said substrate, wherein said semiconductive polymer is a copolymer in which one of the repeat units is a group of formula (I) or a homopolymer in which the repeat unit is a group of formula (I): wherein: A and B are the same or different and each comprises wholly or partially an aryl moiety or a heteroaryl moiety, said moiety in A being fused to the bond a-b and said moiety in B being fused to the bond c-d, and X is a linking unit, X being such that there is a torsion angle of at least 5° between the bond a-b and the bond c-d about the bond b-d. The invention also relates to semiconductive polymers, monomers for preparing same, and methods for preparing random statistical conjugated polymers.
