Abstract
The invention relates to an electroluminescent material of poly(2,6) and poly(2,7)-anthryl vinylderivative and its process for preparing. The material is conjugated polymer constructed by 2,6 and 2,7-anthryl vinyl building block, in which Ar1, Ar2 and Ar of constitutional formula individually stand for arylamine or substituted arylamine with 6-46 carbon atoms, or individually stand for hetero arylamine or substituted hetero arylamine with 4-36 carbon atoms; or Ar1 and Ar2 individually stand for hydrogen atom, cyano-group, halogen atom, and alkoxylation catalyst, dialkylamino, alkyl silicon based or alkyl mercapto with 1-20 carbon atoms; R'and R' individually stand for hydrogen atom and cyano-group, or one stands for hydrogen atom and the other stands for cyano-group. The method consists of Gilch polymerization, Heck coupling or Wittg reaction catalyzed by alkali.
