The reversible isomerization behavior of molecular switches in liquid crystal elastomers (LCEs) usually only can be monotonically repeated, because the motion environment is same for each cycle a permanently cross-linked polymer network. Therefore, achieving tunable photostationary state (PSS) LCE material system significant challenge. Herein, spiropyran-based (SPBM) as switch introduced into system, which constructed typical photo-responsive with behavior. Furthermore, dynamic networks via diselenide bonds endow SPBM this environment, freely or restrictedly depending on size free volume. Thus, programmable photo-response, and program locking unlocking enabled by tuning This post-programming (PPL) strategy may offer new sight promoting higher controllability stimulus-responsive smart materials.
