The invention discloses a preparation method of synthetizing benzpyrole [3, 2-b] carbazole and ramification of the benzpyrole [3, 2-b] carbazole in a high-yield mode and application of the benzpyrole [3, 2-b] carbazole and the ramification of the benzpyrole [3,2-b] carbazole. The product structure of the benzpyrole [3, 2-b] carbazole is expressed in the first formula, and the synthetizing technology is expressed in the second formula. The first technology condition is strongly acidic buffer solution, and the second technology condition is strong alkaline media. R represents an alkyl unit on a chemical compound main body and is in a structure of ethyl, alkyl thiophene, alkyl fluorene, n-octyl, isooctyl, a sulfhydryl group or a naphthenic base. X is in a structure of fluorine, chlorine, bromine, iodine, and the like, and also can be in a structure of boric acid ester, alkyl tin, alkyl magnesium or alkyl copper. Through the synthetizing technology of synthetizing benzpyrole [3, 2-b] carbazole, products expressed
