摘　　要：Photoresponsive materials have been widely used in sensing,bioimaging,molecular switches,information storage,and encryption nowadays.Although a large amount of photoresponsive materials have been reported,the construction of these smart materials into precisely prescribed complex 3D geometries is rarely studied.Here we designed a novel photoresponsive material methyl methacrylate containing triphenylethylene(TrPEF_(2)-MA)that can be directly used for digital light processing(DLP)3D printing.Based on TrPEF_(2)-MA,a series of photoresponsive 3D structures with reversible color switching under ultraviolet/visible light irradiations were fabricated.These complex photoresponsive 3D structures show high resolutions(50μm),excellent repeatability(25 cycles without fatigue),and tunable saturate color degrees.Multicomponent DLP 3D printing processes were also carried out to demonstrate their great properties in information hiding and information-carrying properties.This design strategy for constructing photoresponsive 3D structures is attractive in the area of adaptive camouflage,information hiding,information storage,and flexible electronics.
