An unsymmetrically substituted 4,4′-bis(3-thienyl)biphenyl derivative of 4-(2-ethynyl-3-thienyl)-4′-(3-thienyl)biphenyl type was prepared, utilizing 4-bromo-4′-(2-iodo-3-thienyl) biphenyl as synthetic intermediate. Reaction of 4-(2-ethynyl-3-thienyl)-4′-(3-thienyl) biphenyl with ethylmagnesium bromide followed by treatment with chlorodiphenylphosphine afforded 4-[2-(2-diphenylphosphinoethynyl)-3-t
利用4-溴-4'-制备了4-(2-乙炔基-3-噻吩基)-4'-(3-噻吩基)联苯型的不对称取代的4,4'-双(3-噻吩基)联苯衍生物。 (2-iodo-3-thienyl) 联苯作为合成中间体。4-(2-乙炔基-3-噻吩基)-4'-(3-噻吩基)联苯与溴化乙基镁反应,然后用氯二苯基膦处理,得到4-[2-(2-二苯基膦基乙炔基)-3-噻吩基]-4' -(3-噻吩基)联苯。
