| abstract |
A naphthylanthracene-based polymer comprising a repeating unit of the formula n nwherein: Ar is an aryl or substituted aryl of from 6 to 60 carbon atoms; or a heteroaryl or substituted heteroaryl of from 4 to 60 carbon atoms; n R 1 , R 2 , and R 3 are the same or different, and are each individually hydrogen, or alkyl, or alkenyl, or alkynyl, or alkoxy, or amino, or thioalkyl, or carboxyl, or carbonyl, wherein the alkyl, alkenyl, alkynyl, alkoxy, amino, thioalkyl, carboxy, or carbonyl can have from 1 to 40 carbon atoms; or aryl of from 6 to 60 carbon atoms; or heteroaryl of from 4 to 60 carbon atoms; or F, or Cl , or Br; or a cyano group; or a nitro group, or a sulfonate group; and L is a direct bond between naphthylanthracene and polymer backbone or a carbon linking group having 1 to 40 carbon atoms or a non-carbon linking group. |
