요약 | Vapor-deposited organic glasses are used in a variety of applications, ranging from pharmaceuticals with high bioavailability to the active material for charge mobility in layers of organic light emitting diodes. The glasses studied by the Ediger group are prepared by physical vapor deposition. Depending on the substrate temperature, the as-prepared glasses can have a range of extraordinary properties including high kinetic stability, high density, and suppressed secondary relaxations relative to a glass prepared in the traditional manner of liquid cooling. The work in this thesis focuses on simple organic molecules that serve as model systems for understanding these extraordinary properties that vapor-deposited glasses can have. Specifically, the ability of a series of trialkyl phosphates to form kinetically stable glasses, the proximity of vapor-deposited ethylbenzene glasses to the "ideal glass" state, and physical vapor deposition of the polyamorphic system triphenyl phosphite is described. |
