the 2,2'-positions of BTPE, four BTPE derivatives are prepared which give blue or deep-blue EL emissions when used as emitters in non-doped OLEDs, as the result of the tuned dihedral angles of the biphenyl cores (up to ~89 degrees ), providing a new approach to design AIE luminogens with blue and deep-blue emissions.
通过简单地将不同大小和共轭度的其他基团引入BTPE的2,2'位置,可以制备出四种BTPE衍
生物,这些衍
生物在非掺杂OLED中用作发射极时会发出蓝色或深蓝色EL发射光。
联苯核心的可调二面角(最高约89度),为设计具有蓝色和深蓝色发射光的AIE发光剂提供了一种新方法。
