The invention discloses a three-phase luminous phamid liquid crystal unit as well as a preparation method and application of the three-phase luminous phamid liquid crystal unit. Branch units are arranged at the two ends of the phamid liquid crystal unit, and a long-rod-shaped core is arranged in the middle of the phamid liquid crystal unit. The long-rod-shaped core is composed of a diphenylbutadiyne unit and a diphenylcyano ethylene unit; the former unit is a typical aggregation-induced fluorescence quenching unit, and the latter unit is a typical aggregation-induced light emitting unit; the cyano group is a strong electron withdrawing group, so that the long-rod-shaped probe is of a D-A-pi-A-D structure. The phamid molecule disclosed by the invention can be dissolved in a common solvent; columnar micelles are formed in a selective solvent, and the stability of the micelles is good; and a hexagonal prism-shaped liquid crystal phase is formed in a solid state. In a single molecular state, the D-A effect is str
