The present invention provides an organic luminescent material 9-(4-aryl ethynyl phenyl) carbazoles, prepartion method and uses. The invention uses 9-(4-iodo-benzene) carbazole or derivates thereof as raw materials, under the action of tri-n-butylamine, using dual-triphenylphosphine palladium dichloride/cuprous iodide as catalyst to proceed a Sonogashira coupling reaction with the terminal aryne in tetrahydrofuran for 20 to 50 hours to obtain series of 9-(4-aryl ethynyl phenyl) carbazoles compounds. The compounds can by used as organic luminescent materials.
