N-diarylsubstituted thioureas 20 and thioacetamides 21 a series of heterocyclic analogous of N,N'-perarylated phenylene-1,4-diamines and benzidines was obtained. These compounds represent, as studied by DSC measurements, a new class of hole transporting materials with high thermal stability and high tendency to form stable amorphous states. Moreover, some of the new compounds are, as measured by cyclic voltammetry
从 N,N-二芳基取代的硫脲 20 和硫代乙酰胺 21 开始,获得了一系列类似于 N,N'-过芳基化亚苯基-1,4-二胺和联苯胺的杂环。通过 DSC 测量研究,这些化合物代表了一类新的空穴传输材料,具有高热稳定性和形成稳定无定形状态的高趋势。此外,通过循环伏安法测量,一些新化合物很容易被可逆氧化,表明形成持久的自由基离子。此类化合物通常在其杂环部分完全被芳基取代,已成功用作 OLED 中的空穴传输材料。
