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 one or more linking groups

主权项

1. A composition comprising
a molecular glass mixture of non-polymeric compounds exhibiting a single thermal transition free of phase separation wherein said molecular glass mixture is characterized as (a) amorphous, (b) solid at about 20° C., and (c) comprises at least two different compounds each different compound having at least two linking components, each linking component joining one multi-valent organic nucleus with at least two organic nuclei wherein at least one of the multivalent organic nucleus and the organic nuclei is a charge transport, a luminescent moiety, or a combination thereof.
