Non-crystallizable pi-conjugated molecular glass mixtures, charge transporting molecular glass mixtures, luminescent molecular glass mixtures, or combinations thereof for organic light emitting diodes and other organic electronics and photonics applications

摘要

The present invention provides charge transporting molecular glass mixtures, luminescent molecular glass mixtures, or combinations thereof comprising at least two nonpolymeric compounds each independently corresponding to the structure (R¹Y¹)_p[(Z¹Y²)_mR²Y³]_nZ²Y⁴R³ wherein m is zero or one; n is zero up to an integer at which said compound starts to become a polymer; p is an integer of from one to eight; each R¹ and R³ is independently a monovalent aliphatic or cycloaliphatic hydrocarbon group having 1 to 20 carbon atoms, an aromatic group or a multicyclic aromatic nucleus; R², Z¹, and Z² each independently represent multivalent aliphatic or cycloaliphatic hydrocarbon groups having 1 to 20 carbon atoms or an aromatic group; and Y¹, Y², Y³ and Y⁴ each independently represent a triple bond, a double bond, or a single bond link.
