Abstract
In this study, three bipolar host materials (<italic>i.e.</italic><bold>Py2Cz</bold>, <bold>Py2BFCz</bold>, and <bold>Py2ICz</bold>) for solution-processable green-emitting TADF-OLEDs were synthesized by coupling 2,4-diphenylpyrimidine to <bold>mCP</bold> and modifying the carbazole-donating units in the mCP structure.
