Procedure

Acecyclone (12 g, 33.6 mMole) and 4-biphenylacetylene (9.0 g, 50.5 mMole) were heated to gentle reflux in ortho-dichlorobenzene (100 ML) for 2 hours. The reaction was then cooled, treated with methanol (20 mL) and stirred at room temperature for 1 hour. The resulting yellow solid was filtered off, washed well with methanol and dried. Yield of product ETM1, 17.4 g. Before use in device fabrication, ETM1 was sublimed at 220° C./10−3 mm Hg.
