Sythesis of (E)-4-(4-N,N-diethyl) styryl-thiophenol and Optical Property of Its Nano-Au Composite System

以对氟苯甲醛和二乙胺为原料,合成了4-N,N-二乙胺基苯甲醛(1);1与三苯基膦和KI反应制得碘化4-N,N-二乙胺基苯甲基-三苯基膦(2);2与4-叔丁硫基苯甲醛反应制得(E)-4-(4-叔丁硫基)苯乙烯基-(N,N-二乙基)苯胺(3);3脱叔丁基保护合成了一种新型功能性硫酚配体——(E)-4-(4-N,N-二乙基)苯乙烯基-苯硫酚(4),其结构经1HNMR,IR和MS表征。4与纳米Au配位,制备了一系列4修饰的纳米Au复合体系,并对其光学性质进行了初步探讨。

A new functional thiophenol ligand,（E）-4-（4-N,N-diethyl）styryl-thiophenol（4）,was synthesized from 4-fluorophenylaldehyde and diethylamine by a three-step reaction of 4-fluorophenylaldehyde reacted with triphenylphosphine to obtained [4-（diethylamino）benzyl]triphenylphosphsnium iodide（2）,2 reacted with 4-（tert-butylthiol）benzaldehyde to obtained the（E）-4-[4-（tert-butylthio）styryl]-N,N-diethylbenzenamine（3） by ullman reaction and then deprotection of the group of tert-butyl of 3.The structure was characterized by 1H NMR,MS and IR.The nano-Au was modified using 4 as a ligand to obtain nano-Au-4 composite system and the optical property of the system was preliminarily investigated.
