pertaining to these systems have been restricted almost exclusively to amorphous solids based on a single molecule. In this study, we found that, while the 2,4,6-bis(4-tert-butylphenyl)phenoxyl radical (2M) and its dimer (2D) did not give single-component amorphous solids, they rapidly formed the corresponding binary amorphous solid IIa following their condensation from benzene, dichloromethane, chloroform
尽管分子无定形材料代表了固态化学研究的重要领域,但有关这些系统的研究几乎仅限于基于单个分子的无定形固体。在这项研究中,我们发现,虽然2,4,6-双(4-叔丁基苯基)苯氧基(2 M)及其二聚体(2 D)并未产生单组分非晶态固体,但它们迅速形成了从苯,二氯甲烷,氯仿和乙酸乙酯溶液缩合后得到相应的二元无定形固体IIa。IIa的形成可以归因于2 M和2的良好溶解度D在这些溶剂中以及这些无定形固体的高填充效率。当将2 D( IIb)晶体一起研磨时,也会获得IIa。IIa的固态形成不仅涉及2 M和2 D的位置交换,而且还涉及化学交换。
