Application

1,4-Bis[4-(6-acryloyloxyhexyloxy)benzoyloxy]-2-methylbenzene (RM82) is a known precursor for liquid crystal elastomer (LCEs) inks that can be direct-write printed into 3D structures capable of reversible changes in shape, i.e., four-dimensional-printed (4DP) structures . LCE actuators (LCEAs) using RM82 showed both thermal , photo and chemical responsiveness, which may enable new generations of soft robotics , implantable medical devices and dynamic functional arquitecture, such as photoswitches . RM82 has also been used to create the mesogenic order in liquid crystalline vitrimers, allowing postpolymerization processing, while also minimizing unwanted creep during actuation.
This product can be used in Material Jetting or Vat polymerization 3D printing techniques.

Oscillating materials that adapt their shapes in response to external stimuli are of interest for emerging applications in medicine and robotics. For example, liquid-crystal networks can be programmed to undergo stimulus-induced deformations in various geometries, including in response to light.

Interfacing molecular photoswitches with liquid crystal polymers enables the amplification of their nanoscale motion into macroscopic shape transformations. Typically, the mechanism responsible for actuation involves light-induced molecular disorder. Here, we demonstrate that bistable hydrazones can drive (chiral) shape transformations in
