摘要：
Block copolymer photonic crystals comprising polyelectrolyte hydrogels exhibit strong reflective multicolors in response to near-UV radiation. Due to unique volume transition of swollen gels, the photonic gels show high photosensitivity, and which can be widely tunable by exchanging counter-anions. Multicolor photonic patterns created by photolithography can be repeatedly fixated and reactivated by sequentially exchanging counter-anions with different photosensitivity.
