PURPOSE: Provided is a method for manufacturing an electroluminescent polymer which contains silicon at its main chain as well as cyano group, shows good solubility, emits green light at 480nm, and has low driving power, about 7V. CONSTITUTION: A method for manufacturing di-(p-cyanomethylphenyl)dialkyl/aryl silane of the formula (I) is comprised of the next steps of: i) reacting dialkyldichlorosilane or diaryldichlorosilane with p-bromotoluene in the presence of alkali metal or alkaline earth metal as catalyst and chloroform as solvent to manufacture di-p-tolyldialkyl/aryl silane; and ii) reacting di-p-tolyldialkyl/aryl silane with sodium cyanides in the presence of chloroform as solvent to manufacture di-(p-cyanomethylphenyl)dialkyl/aryl silane of the formula (I). In the formula (I), R and R' are the same or different, and an alkyl or aryl group. The electroluminescent polymer of the formula(II) is manufactured by polymerizing the compound of the formula (I).
