PHOTOACTIVE COMPOSITION AND ELECTRONIC DEVICE MADE WITH THE COMPOSITION

摘要

There is provided a photoactive composition including: (a) a first host material having a HOMO energy level shallower than or equal to −5.6 eV and having a Tg greater than 95° C.; (b) a second host material having a LUMO deeper than −2.0 eV; and (c) an electroluminescent dopant material. The weight ratio of first host material to second host material is in the range of 99:1 to 1.5:1.
