Abstract

Block copolymers bearing carbazole moieties in thin films nicely demonstrated vertical or horizontal lamellar structure depending on the process condition. The vertical lamellar structure revealed permanent memory behavior, where the horizontal lamellar structure exhibited volatile memory behavior.
