9,10Bis(trimethylsilylethynyl) anthracene was prepared by a coupling reaction of dibromoanthracene dibromobenzene and trimethylsilylethyne,using PdCl2(PPh3)2 and CuI as catalysts. A mixed solvent of THF/diethylamide was used as the media of the coupling reaction. The product was obtained with desired yields and it was characterized by IR,UV,1HNMR.
