摘要
Photodeformable materials are a class of molecules that can convert photon energy into mechanical energy,which have attracted tremendous attention in the last few decades.Owing to their unique photoinduced deformable properties,including fast lightresponse and diverse mechanical behaviors,photodeformable materials have exhibited great potential in many practical applications such as actuators,photoswitches,artificial muscles,and bioimaging.In this review,we sort out the current state of photodeformable crystals and classify them into six categories by molecular structures:diarylethenes,azobenzenes,anthracenes,olefins,triarylethylenes,and other systems.Three distinct light-responsive mechanisms,photocyclization,trans-cis isomerization,and photodimerization,are revealed to play significant roles in the molecular photodeformation.Their corresponding photodeformable behaviors such as twisting,bending,hopping,bursting,and curling,as well as the potential applications,are also discussed.Furthermore,the challenges and prospective development directions of photodeformable crystals are highlighted.
