Significance Organic glasses are useful, versatile materials for current and future organic electronic technologies. They are nonequilibrium materials, so a single-component system can be processed in different ways to create a wide range of solids with diverse structural and optical properties. In this work, we use physical vapor deposition to prepare glasses with structure similar to that of an aligned smectic liquid crystal from a molecule that does not have any liquid crystal phases. This shows the potential to create highly structured glasses from a wide range of molecules.
