摘要
2,2′,7,7′-四溴-9,9′-螺二芴是合成有机电致发光材料的重要中间体.文章以9,9′-螺二芴为原料,过量的液溴为溴源,无催化剂作用,室温下合成了2,2′,7,7′-四溴-9,9′-螺二芴,产率为63.3%.用核磁共振氢谱对产物进行了结构表征.
2,2′,7,7′-tetrabromo-9,9′-spirobifluorene(TBSBF) is the key intermediate of organic electroluminescene.TBSBF was synthesized from 9,9′-spirobifluorene(SBF) catalyst-free with an excess of bromine in chloroform at room temperature in a yield of 63.3 %.The product was characterized by HNMR.
