Photochromic Behavior in the Molecular Glass of 4, 4', 4"-Tris(3-methylphenyphenylamino)triphenylamine
For the purpose of gaining information on the microstructure of molecular glasses, photochromic behavior of 4-dimethylaminoazobenzene (DAAB) in the molecular glass of 4,4′,4″-tris(3-methylphenylphenylamino)triphenylamine (<I>m</I>-MTDATA) was studied in comparison with that in a polystyrene matrix and in a benzene solution. The results strongly suggest that the local free volume in the molecular glass of <I>m</I>-MTDATA is smaller than that in the polystyrene glass.
