Abstract

Evaporation of mixed solution of 2,4,6-Tris(4-Tert-butylphenyl)phenoxyl 1M and its phenol analogue 1OH yielded a solid solution (III), where 1OH : 1M = 0.70 : 0.30, which was isomorphic to crystal of 1OH (II). In contrast, slow evaporation of 1M concomitant with gradual decomposition giving 1OH yielded crystal-glass composite (IV) consisting of 1OH : 1M with a molar ratio of 0.40 : 0.60. The outer crystal region of IV was attributed to solid solution of 1OH and 1M, while the inner glassy region to amorphous consisting of 1M and its dimer 1D (I).
