\nRésumé: Mole
 cular glasses are small molecules that can readily form glassy phases and 
 do not recrystallize on standing. This is typically due to very slow cryst
 allization kinetics that stem from irregular molecular structures and poor
  packing. As a result\, molecular glasses are desirable for applications i
 nvolving thin films\, and constitute an appealing alternative to polymers 
 because of their monodisperse nature.
\n 
\nOur group has developed a ser
 ies of triazine-based molecular glasses that show outstanding resistance t
 o crystallization\, and has used derivatives containing reactive functiona
 l groups that can be covalently bonded to chromophores to synthesize glass
 -forming adducts.
\n 
\nThis strategy has been used to synthesize glass-f
 orming donor and acceptor materials for organic photovoltaics (OPV). While
  OPV cells typically use polycrystalline materials that yield a bulk heter
 ojunction architecture composed of small domains\, optimal performance is 
 highly dependent on processing conditions to achieve the optimal domain si
 ze. For simplifying the fabrication process\, it may be worthwhile to use 
 amorphous materials for the active layer instead. The results of devices i
 ncorporating these materials in either partially or fully amorphous binary
  or ternary active layers will be presented.
