    • Photostability can be significantly modulated by molecular packing in glasses 

      Ediger, Mark; de Pablo, Juan; Antony, Lucas; Qiu, Yue (Journal of the American Chemical Society, 2016-08-12)
      While previous work has demonstrated that molecular packing in organic crystals can strongly influence photochemical stability, efforts to tune photostability in amorphous materials have shown much smaller effects. Here ...
    • Tenfold increase in the photostability of an azobenzene guest in vapor-deposited glass mixtures 

      Ediger, Mark; de Pablo, Juan; Torkelson, John; Antony, Lucas; Qiu, Yue (2018-09-10)
      Improvements to the photostability of organic glasses for use in electronic applications have generally relied on modification of chemical structure. We show here that the photostability of a guest molecule can also be ...
    • Vapor-Deposited Glasses with Long-Range Columnar Liquid Crystalline Order 

      Gujral, Ankit; Gomez, Jaritza; Ruan, Shigang; Toney, Michael F.; Bock, Harold; Yu, Lian; Ediger, M. D. (American Chemical Society, 2017-10-04)
      Anisotropic molecular packing, particularly in highly ordered liquid crystalline arrangements, has the potential for optimizing performance in organic electronic and optoelectronic applications. Here we show that physical ...
    • Vapor-deposited Organic Glasses Exhibit Enhanced Stability Against Photodegradation 

      Ediger, Mark; Dalal, Shakeel; Qiu, Yue (Soft Matter, 2018-03-25)
      Photochemically stable solids are in demand for applications in organic electronics. Previous work has established the importance of the molecular packing environment by demonstrating that different crystal polymorphs ...
