Procedure: Turning now to FIG. 1, a four step synthetic route for the preparation of α,δ-bis(4-hydroxy)sexiphenylene, in accordance with an embodiment of the present invention, is presented. Thus in a first step, a first solution is prepared by adding an appropriate amount of 4-methoxyphenylacetic acid to an aqueous solution of sodium carbonate. To this first solution is added an appropriate amount of a second solution, aqueous manganese chloride, to produce a pink foamy mixture. This mixture is washed with water and filtered to yield a pink powder, now comprising sodium phenylacetate and manganese dichloride hydrate. This pink powder is distilled at 300-320° C. under vacuum to effect a thermally induced dehydrative coupling reaction to give an excellent yield (72%) of white crystals of 1,3-bis(4-methoxyphenyl)propanone, having a melting point of between approximately 75-76° C. a four step synthetic route for the preparation of α,δ-bis(4-hydroxy)sexiphenylene Thus in a first step, a first solution is prepared to produce a pink foamy mixture This mixture is washed with water filtered
