with the synthesis of tertiary amides fromcarboxylicacids, and successful results were only obtained under forcing conditions."-15 Therefore, an efficient conversion of carboxylicacids into tertiary amides is still in demand to synthesize various organic compounds. In continuation to our studies on the use of trichloromethyl chloroformate in organic synthesis,I6 we report herein a mild and convenient

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.
