BTP (2,2′‐bistriphenylenyl) emits very strong blue light in the solid state and in solution and shows excellent physical properties, such as a very good thermal stability and a high melting point. Electroluminescent devices using BTP as the blue emitter show high brightness, good external quantum and current efficiency, and excellent CIE coordinates.

Treatment of various 1,4-epoxy-1,4-dihydroarenes with trichlorosilane in toluene in the presence of a palladium complex affords the corresponding biaryls in good to excellent yields. The process appears to occur via a novel palladium-catalyzed hydrosilylative dimerization of 1,4-epoxy-1,4-dihydroarenes and subsequent elimination of HOSiCl(3) and H(2)O.
