In recent years, graphdiyne and its derivatives with fascinating

electro-optic properties have attracted tremendous scientific

attention. Here we design and synthesize a graphdiyne-derived

discotic liquid crystal material by decorating six wedge-shaped

3,4,5-tris(dodecyloxy)benzoate groups on the fundamental structural

unit of graphdiyne, the dehydrotribenzo[18]annulene core. This

graphdiyne-derived liquid crystal material exhibits a cubic phase and

a hexagonal columnar phase at varied temperatures. Most interestingly,

this molecule displays a tunable phase-dependent photoluminescence

behavior. Under the irradiation of 365 nm wavelength ultraviolet light,

the luminescent material emits pale blue, green and azure light in the

cubic, hexagonal columnar and isotropic phases respectively. This

graphdiyne-derived discotic liquid crystal with excellent optical characteristics might have application potentials in organic optoelectronic

functional materials and devices.
