A chiral luminescent liquid crystal with a tolane unit

<p>We have synthesised a chiral liquid crystal with a tolane unit that exhibits intense fluorescence in both solution and the solid states. The liquid crystal can form the enantiotropic twist-grain boundary A (TGB<sub>A</sub>*) and Blue II phases, and the helical pitch of the TGB<sub>A</sub>* phase decreases with an increasing temperature.</p>
