摘要： Provided is a composition A that includes: a first dopant; and a first host; where the first dopant has a HOMO energy HOMODopant and a LUMO energy LUMODopant; the first host has a HOMO energy HOMOHost and a LUMO energy LUMOHost; |LUMOHost - HOMODopant| = X1; ILUMODopant - HOMOHost| = X2; the first dopant has an optical bandgap energy, Y; at least one of XI and X2 is less than or equal to Y + 0.026 eV; the composition A has a vertical dipole ratio VDR(A); composition B is a reference composition comprising the first dopant and a second host, wherein the second host is
the composition B having a vertical dipole ratio VDR(B); the ratio of the first dopant and the first host in the composition A is identical to the ratio of the first dopant and second host in the composition B; and VDR(A) - VDR(B) is ≥ 0.05.-

摘要： Provided are OLEDs and related electronic devices that utilize these OLED devices. The OLED includes an emissive region that includes a sensitizer and an acceptor, where the sensitizer has a lowest excitation energy state E T 1 , and is capable of harvesting triplet excitons; where the acceptor is capable of receiving energy from the sensitizer and functioning as a fluorescent emitter at room temperature; where the acceptor has a first moiety and a second moiety, the first moiety having a lowest singlet excitation energy state E S 1 A and a lowest triplet excitation energy state E T 1 A , and the second moiety having a lowest singlet excitation energy state E S 1 B and a lowest triplet excitation energy state E T 1 B ; and where E S 1 A S 1 B , E T 1 A > E T 1 B , and E T 1 > E S 1 A .
