Since 30 years, liquid crystalline elastomers (LCEs) have been attracting the attention of many researchers thanks to their anisotropic mol. structure which allows them to build up artificial muscles. Possible applications span from soft robotics to biomedical or tunable optical devices. The power of thiol-yne click chem. was recently demonstrated in the preparation of smart polymers, in particular LCEs, in which the mesogenic units are incorporated both in the main-chain and as pendant groups. To enrich the library of available LCE materials, in this work, several liquid crystalline dithiols and alkynes have been synthesized and copolymerized to obtain elastomers with different thermomech. properties. The architecture of the main chain was found to play a prominent role in modulating the clearing point in a range of 60°C, whereas only a minor contribution is given by the mesogens in the side chain. On the other hand, the mech. response resulted highly sensitive to fine details of the side-chain structure. Accordingly, the present study not only improves the basic understanding of the chem.-phys. properties of LCEs but paves the way to the preparation of multicomponent actuators able to deform in different temperature ranges, thus ultimately leading to complex soft robotic operations. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Computed Properties of C13H12O2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Computed Properties of C13H12O2
