Patent abstract
A method of synthesizing a poly(9,9-disubstituted-fluorene) includes reacting a 9,9-disubstituted-fluorene with an alkyl lithium in the presence of a catalytic amount of a nickel amine complex. The 9,9-disubstituted-fluorene includes solubility-enhancing substituents in the 9-position and leaving groups in the 2-position and the 7-position. The product poly(9,9-disubstituted-fluorene)s are fluorescent conjugated polymers that are useful as, for example, blue light-emitting materials.
