The invention discloses a method for controlling the morphology of a porous aromatic framework material based on a Sonogashira-Hagihara coupling polycondensation reaction. According to the invention,tetrakis(triphenylphosphine)palladium and cuprous iodide are used as catalysts, triethylamine and N,N'-dimethylformamide are used as solvents, and a tubular porous aromatic skeleton T-LNU and a blockyporous aromatic skeleton B-LNU with controllable morphology are obtained by controlling a feeding ratio of monomers including 1,4-dibromonaphthalene and 1,4-diethynylbenzene; and a porous carbon material T-LNU-X or B-LNU-X obtained after direct carbonization of the tubular porous aromatic skeleton T-LNU and the blocky porous aromatic skeleton B-LNU is applied to an electrode material of a supercapacitor, and the electrode material with a hollow tubular structure is more beneficial for immersion of an electrolyte into a tubular interior and for electron transmission. By simply changing a raw material feeding ratio, pro
