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.
