在光致变色二噻吩乙烯中引入磷原子,1,2-双(5-氯-2-甲基噻吩-3-基)环戊烯在正丁基锂存在下进行锂化,分别与Ph2PCl或Cy2PCl反应得到相应的二噻吩乙烯双(膦)配体。双(膦)配体经H2O2氧化、S8硫化和Se硒化,并对其结构进行了表征。
A phosphor atom was introduced into photochromic dithienylethene and the corresponding dithienylethene bis(phosphine)ligands were obtained by the lithiation of 1,2-bis-(5-chloro-2-methylthien-3-yl) cyclopentene in the presence of n-butyllithium which were then reacted with Ph2PCl or Cy2PCl, respectively. The bis(phosphine)ligands were oxidised with H2O2, sulfurated by S8and selenated by Se and their structures were characterized.
