Embodiments of the present invention provide charge-transporting molecular glass mixtures, luminescent molecular glass mixtures, and combinations thereof with thermal properties that can be controlled independent of the structure of the core charge-transporting group, the luminescent group, or combination thereof. Each of the charge-transporting molecular glass mixture, the luminescent molecular glass mixture, and combinations thereof are defined as a mixture of compatible organic monomeric molecules with an infinitely low crystallization rate under the most favorable conditions. These can be formed in a one-part reaction of a mixture of a set of mono-functional materials having a common functionality with another set of mono-functional materials having a different common functionality; whereas the functionality of the first set is reactive to the functionality of the second set to yield an asymmetric condensation molecule. The “non-crystallizability” of the mixture is controlled by the asymmetric nature of and the number of the molecules of the mixture. |
