TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The molecular glass mixture of non-polymeric compounds where the molecular glass mixture further comprises at least two different compounds each conforming to the formula (R1Y1)p((Z1Y2)mR2Y3)nZ2Y4R3..m=0 or 1;n=the number of recurring units in the compound, and is zero up to, but not including, an integer at which the compound starts to become a polymer;p=1-8;R1 and R3=each independently a monovalent aliphatic or cycloaliphatic hydrocarbon group having 1-20 carbon atoms or an aromatic group;R2, Z1, and Z2=each independently multivalent aliphatic or cycloaliphatic hydrocarbon groups having 1-20 carbon atoms or an aromatic group; andY1-Y4=each independently a linking group; provided that at least one of R1, Z1, R2, Z2, and R3 is a multicyclic aromatic nucleus.The molecular glass mixture is solvent-coatable, or vacuum-coatable. All the components of the molecular glass mixture are asymmetric. The molecular glass mixture is noncrystallizable. The composition further comprises mixing a non-equilibrium molecular glass, a crystallizable molecule, or its combination with the noncrystallizable molecular glass mixture in a proper ratio to obtain a new noncrystallizable glass mixture, where the non-equilibrium glass, the crystallizable molecule, or its combination is charge transporting, luminescent, or its combination. The molecular glass mixture is soluble in a solvent taken from water, acetone, 1-butanol, ethanol, 2-propanol, ethyl acetate, methanol, isopropyl acetate, acetonitrile, tetrahydrofuran, 2-methyltetrahydrofuran, dimethyl sulfoxide, acetic acid, and xylene. The asymmetric bisanhydride is 2,3,3',4'-biphenyltetracarboxylic acid dianhydride of formula 1.
