WIPO Patent Application WO/2015/148327

Inventor: MOLAIRE, Michel Frantz

Abstract
The present invention provides charge transporting molecular glass mixtures, luminescent molecular glass mixtures, or combinations hereof comprising at least two nonpolymeric compounds each independently 5 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, 10 and Z2 each independently represent ultivalent 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.
