- •
Properties of a new blue emitting material, i.e. 3,12-dimethoxy-5,6,9,10-tetrahydro-7,8-dicyano-[5]helicene (DTDH), were studied and reported.
- •
Blue OLEDs were fabricated using DTDH as an emissive material.
- •
White OLEDs were fabricated by combining emission spectra of a pure DTDH and of an exciplex between DTDH and NPB.
