Taking 2 ,5‐dibromo‐4‐hexylbenzenamine as the starting material ,diynyl substituted aniline is obtained by using Pd/Cu catalyzed Sonogashira coupling reaction with triisopropylsilicon alkyne . The resulted compounds can be selectively deprotected by TBAF ,which are subjected to the [2 + 2] cycloaddition reaction with tetracyanoethylene to provide compounds 5 and 6 .The structures of the compounds are characterized by 1 H NMR ,13C NMR and FTIR .The analysis of ultraviolet absorption spectrum finds that the compounds 5 and 6 have significant solvent effect . The electrochemical tests indicate that the target compounds are suitable to be used as novel OLED materials .
