通过简单地在BTPE的2，2 '-位引入不同大小和共轭度的基团，制备了四种BTPE衍生物，它们在用作非掺杂OLED的发光体时，由于联苯核的二面角（高达89度）的调节，产生蓝色或深蓝色的EL发射，为设计具有蓝色和深蓝色发射的AIE发光体提供了一种新的方法。
By simply introducing additional groups with different size and conjugation degree to 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 similar to 89 degrees), providing a new approach to design AIE luminogens with blue and deep-blue emissions.
