NOVELTY - Method of synthesizing an aryl polymer comprises: 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 the first mixture with a second dibromoaryl moiety in the presence of a phase transfer agent.    USE - The aryl polymer is useful in an organic electronic device and in an article that is useful for the manufacture of the organic electronic device (all claimed), where the organic electronic device includes devices that convert electrical energy into radiation e.g. a light-emitting diode, light-emitting diode display, diode laser or lighting panel; devices that detect signals through electronic processes e.g. photodetectors photoconductive cells, photoresistors, photoswitches, phototransistors, phototubes, infrared detectors or biosensors; devices that convert radiation into electrical energy e.g. a photovoltaic device or solar cell; devices that include one or more electronic components that include one or more organic semiconductor layers e.g. transistor or diode; and coating materials for memory storage devices, antistatic films, biosensors, electrochromic devices, solid electrolyte capacitors, energy storage devices such as a rechargeable battery, and electromagnetic shielding applications.    ADVANTAGE - The preparation method does not include the additional step of further purification or isolation, i.e. the crude product of the reaction mixture is allowed to react with the further reactant. The in situ reaction between the aryl boronic ester and second dibromoaryl molecule occurs without purifying or isolating the formed intermediate product (aryl diboronic esters) confers significant benefits including the saving of time and expense.
