摘要
A design rule of the acceptor material of exciplexes was studied by synthesizing two acceptor materials with only acceptor moieties and with both a donor and an acceptor simultaneously. Molecular calculation and photophysical measurements of the exciplexes revealed that the donor acceptor type acceptor materials promoted the exciplex formation by charge transfer character and increased the photoluminescence quantum yield of the exciplexes. The combination of a donor material and the donor acceptor type acceptor material achieved a high quantum efficiency of 12.6% in the green exciplex devices.
