摘要：Dynamic photoprogramming of soft helical microstructures with unique photonic attributes allows for optical calculator, information encoding, and planar optical devices. However, achieving the highly desirable multiple degrees of freedom (DOFs)-like wavelength and photonic band is still a long-standing challenge. Herein, we introduce an intrinsically chiral copper-gated photoswitch to develop dynamic photoprogramming of liquid-crystal helical microstructures, achieving multiple optical DOFs including wavelength and the manipulable range of photonic bands and photoswitch-induced fluorescence intensity, along with excellent thermal stability and robust fatigue resistance. These unique characteristics stem from the ingenious coupling of molecular chirality fluctuations and the copper-gated effect with light irradiation, which has been developed to bridge the molecular and wavelength scales. Such an elegant photoprogrammable microstructure promotes optical information processing, including a photorewritable logic calculator and adaptive camouflage framework. The multiple DOFs photo programming with a copper-gated photoswitch paves a promising avenue toward non-contactable, stimuli-activated soft helical microstructures, especially for smart responsive materials and soft condensed physics.
