| 1. A method of synthesizing an aryl polymer, comprising:
reacting a first dibromoaryl moiety with a diboron ester in the presence of palladium to yield a first mixture; and
without substantially purifying the first mixture, reacting said first mixture with a second dibromoaryl moiety in the presence
of a phase transfer agent.
