摘要:通过 2-溴芴 (1) 和 2,7-氟代硼酸酯衍生物 (3) 的 Suzuki 偶联反应合成了新的三 (9,9-二芳基芴),具有高分离产率 (63-86%).Ter(9,9'-Spirobifluorene) (4Aa) 的 X 射线结构分析表明共轭发色团采用螺旋构象.这种构象有效地释放芴部分之间的空间相互作用并防止发色团间相互作用.在芴的 C9 位置引入芳基非常有利于这些低聚物的热稳定性和形态稳定性.这些三芴在溶液(大约 100%)和固态(66-90%)中都表现出强烈的蓝色荧光,具有出色的量子产率,并且具有有趣的可逆氧化还原特性.使用 4Aa 和 4Cc 作为发射器以及空穴传输器制造了高效的蓝光 Oled 器件.该器件具有低开启电压(约 3 V)和高 El 外量子效率(2.5-3%).
