一种新的锌基成环方法以较高的产率区域选择性地合成了2，3，6，7-四芳基苯并[1，2-B：4，5-B ']二呋喃。使用这些四芳基苯并二呋喃作为空穴传输材料的有机电致发光器件显示出比使用α-NPD，目前的标准HTM的那些更好的性能。四芳基苯并二呋喃的空穴漂移迁移率和玻璃化转变温度也被发现优于α-NPD。
A new zinc-based annulation method produced regioselectively a variety of 2,3,6,7-tetraarylbenzo[1,2-b :4,5-b ']difurans in good yields. The organic electroluminescent devices using these tetraarylbenzodifurans as hole-transporting materials showed better performance than those using alpha-NPD, the current standard HTM. The hole drift mobility and the glass-transition temperatures of the tetraarylbenzodifurans were also found to be better than those of alpha-NPD.
