Mp. These two compounds are amorphous in solid state. The X-ray powder diffraction pattern of 4f further confirmed that it is truly amorphous throughout the temperature range in which it is solid. Therefore, we have demonstrated that a low molecular weight organic solid can be amorphous. This is an important aspect in the preparation of morphologically stable amorphous thin film.

采用Pd(0)催化CN键形成方法合成了一系列N,N,N,N'-四芳基(Ar 1 2 Ar 2 2 )-1,1'-联苯-4,4'-二胺。测量了物理性质,包括玻璃化转变温度(Tg)、熔点(Mp)和氧化电位。对于 Ar' = 2-萘基和 Ar 2 = 3-甲苯 (4f) 和 Ar 2 = 3-乙基苯基 (4h),DSC 图表明它们具有 Tg,但没有可观察到的 Mp。这两种化合物在固态下是无定形的。4f 的 X 射线粉末衍射图进一步证实它在整个温度范围内都是无定形的。因此,我们已经证明低分子量有机固体可以是无定形的。这是制备形态稳定的非晶薄膜的一个重要方面。Ar 1 = Ph 的其他化合物,1-萘基而 Ar 2 = 3-甲苯或 3-乙基苯基是正常的化合物,当通过快速冷却它们的熔体以玻璃态制备时具有 Tg 和 Mp。Ar 1 = 1-萘基和2-萘基且相同的Ar 2 化合物的氧化电位完全相同。分子结构
