A series of poly(norbornene-dicarboximide)s were synthesized by ROMP.
Introducing various acceptors to tricarbazole can achieve different color emission.
The HOMO levels of polymers are close to the most common hole injection materials.
The LUMO level of polymer with the cyano group is very close to the material of Alq3.
Polymers possess high thermal stability with decomposition temperature over 400 °C.
