<jats:title>Abstract</jats:title><jats:p>Although the shape‐changing capabilities of LCEs hold great potential for applications ranging from micropumps to artificial muscles, customization of the LCE functionality to the applications' requirements is still a challenge. It is studied whether the orientation of NMC‐LCPs and NMC‐LCEs based on 2‐<jats:italic>tert‐</jats:italic>butyl‐1,4‐bis[4‐(4‐pentenyloxy)benzoyl]hydroquinone can be enhanced by copolymerization with 2‐methyl‐1,4‐bis[4‐(4‐pentenyloxy)benzoyl]hydroquinone or 2,6‐bis[4‐(4‐pentenyl‐oxy)‐benzoyl]anthracene. An increasing content of the comonomers stabilizes the nematic phase, which enables a tailoring of <jats:italic>T</jats:italic><jats:sub>NI</jats:sub> for the NMC‐LCP between 45 and 68 °C, while for the NMC‐LCE <jats:italic>T</jats:italic><jats:sub>NI</jats:sub> ranges between 69 and 76 °C. In addition, NMC‐LCE show an increased actuation performance. <jats:boxed-text content-type="graphic" position="anchor"><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" mimetype="image/jpeg" position="anchor" specific-use="enlarged-web-image" xlink:href="graphic/mgra001.jpg"><jats:alt-text>magnified image</jats:alt-text></jats:graphic></jats:boxed-text></jats:p>
