主　　题：properties prescribed attractive 

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