The invention belongs to the technical field of new chemical materials, and particularly relates to a carbazole structural unit-containing porous aromatic skeleton material which is prepared by the following steps: under the condition of nitrogen, adding a bromo-containing carbazole organic compound and 1,3,5-triacetenyl benzene into a reaction container, adding a catalyst and an organic solvent to perform a reaction at 80 DEG C for 3 days; after the reaction is finished, cooling a reaction product to room temperature, and respectively washing the reaction product with N,N'-dimethylformamide,tetrahydrofuran, acetone, dichloromethane and methanol for multiple times to obtain a crude product; carrying out Soxhlet extraction on the crude product by using tetrahydrofuran, dichloromethane andmethanol; and carrying out vacuum drying at 90 DEG C for 10 hours to obtain the porous aromatic framework material LNUs. According to the method, cheap monomers are adopted, reaction conditions are mild, and the reaction can b
