Abstract

Methyl-substituted derivatives of 1, 3, 5-tris (diphenylamino) benzene (TDAB) are found to show unique solid-state morphology, as characterized by differential scanning calorimetry and X-ray diffraction. These compounds readily form stable amorphous glasses having glass-transition temperatures of ca. 50° C. p-Methyl-substituted TDAB exhibits polymorphism.
