Patent ID: 7005484

Claim:
A method for making a polymer or oligomer comprising the steps of: (a) making a first monomer comprising a substituted aromatic or heteroaromatic group by: (i) providing an aromatic or heteroaromatic group substituted with first and second director groups; (ii) performing metalation by replacement of hydrogen at a first position on the aromatic or heteroaromatic group; and, (iii) performing electrophilic substitution so as to provide a first substituent group at the first position; and (b) contacting in a reaction mixture the first monomer with at least two further monomers that independently are the same or different from the first monomer under conditions so as to form a polymer or oligomer; wherein the nature and positions of the first and second director groups regioselect the first position to be ortho to the first director group.
