A new class of n-electron starburst molecules, 1,3,5-tris(4halogenophenylphenylamino) benzenes, are synthesized for use as amorphous molecular materials. It was found that they readily form amorphous glasses, whereas the parent compound 1,3,5-tris(diphenylamino) benzene instantly crystallizes and that the ease of glass formation, glasstransition temperature, and stability of the glassy state are greatly affected by the type of halogen substituent.
