Small molecular weight amorphous phase forming materials is a new emerging class of electro optical materials. While general principles linking molecular structure and material thermal and amorphous phase stability characteristics remain unresolved, molecular glasses have several considerable advantages such as relatively simple synthesis and purification, increased chromophore density and well defined structure. A wide spread strategy for obtaining molecular compounds capable of forming stable glasses involves preventing the molecules from interacting together in a strong and directional fashion. In particular the presence of arene rich starburst structural fragments is successfully used to obtain such materials, where crystallization and aggregation process is hindered by sterical demands of conformationally rigid bulky substitutes or insufficient solid phase packing due to the shape of molecules. One of promising strategies for obtaining molecular glasses is the modular approach where a core molecule not capable of glass formation is further functionalized with building blocks preventing the crystallization. Substituents like N,N-diphenylhydrazone [1] and triazines [2] are successfully used to obtain amorphous materials.
