Fluorene-Based Asymmetric Bipolar Universal Hosts for White Organic Light Emitting Devices

Two new bipolar host molecules composed of hole‐transporting carbazole and electron‐transporting cyano (CzFCN) or oxadiazole (CzFOxa)‐substituted fluorenes are synthesized and characterized. The non‐conjugated connections, via an sp3‐hybridized carbon, effectively block the electronic interactions b...
