Novel low-molecular-weight amorphous organic glasses based on triphenylamine core end-capped by either di(4-methoxyphenyl)amino or 3,6-dimethoxycarbazol-N-yl groups have been synthesized and characterized. The molecules exhibit high glass-transition temperatures (74–151 °C), excellent thermal stability, and are soluble in common organic solvents. Moreover, most of them absorb mainly in UV domain. These
合成并表征了基于被二(4-甲氧基苯基)氨基或3,6-二甲氧基咔唑-N-基封端的三苯胺核的新型低分子量无定形有机玻璃。这些分子表现出较高的玻璃化转变温度(74–151°C),出色的热稳定性,并且可溶于常见的有机溶剂。而且,它们中的大多数主要在UV域吸收。这些星形三苯胺衍生物是用于固态染料敏化太阳能电池应用的有前途的空穴传输材料。
