Abstract

Amphoteric one-dimensional photonic crystal (PC) based on polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymer was developed by intercalation polymerization of acrylic acid and 2-hydroxyethyl methacrylate in the partly quaternized P2VP (QP2VP) layers. The amphoteric PC reversibly exhibits a high first Bragg peak position (λ_max > 700 nm) at both acidic and basic pH values where the QP2VP layers are positively and negatively charged respectively. The minimum λ_max (300 nm) at pH 5.5 can be observed due to charge screening. The PC with a U-shaped pH response also shows good durability.
