PURPOSE: Diaminocarbazole derivatives are provided to be advantageously used as intermediates in a polyazomethine preparation. Polyazomethines obtained by using the diaminocarbazole derivatives have excellent solubility in organic solvent or mixed organic solvent with water, thereby improving the processability and applications of the electroconductive polymer material obtained by doping the polyazomethine. CONSTITUTION: The diaminocarbazole derivatives are represented by a formula 1, wherein R is hydrogen, alkyl having C50 or less, hydroxyalkyl, alkylarylhydroxy, arylhydroxy, carboxyalkyl, alkylester, arylester and alkylarylester group. The diaminocarbazole derivatives are produced by: substituting the hydrogen of N-H bond in the carbazole ring with one selected from alkyl, hydroxyalkyl, alkylarylhydroxy, arylhydroxy, carboxyalkyl, alkylester, arylester and alkylarylester group in the presence of sodium hydride or potassium carbonate as a catalyst; dissolving the resulted N-substituted carbazole derivatives into a mixed solvent of acetic acid and anhydride thereof to introduce two nitro groups by using Cu(NO3)2·2.5H2O as a nitrating agent; dissolving the resulted product into ethyl alcohol and hydrochloric acid and adding SnCl2 thereto to reduce the nitro groups to imino groups. Polyazomethines are represented by a formula 2, wherein R is hydrogen, alkyl having C50 or less, hydroxyalkyl, alkylarylhydroxy, arylhydroxy, carboxyalkyl, alkylester, arylester and alkylarylester group; Z is N-R1 or CR2R3, wherein R1, R2 and R3, being independent from each other, are same as defined for R; and n is 2-500000.
