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-blueemissions.
