Progress in the Studies of Multifunctional Triphenylamine Materials

Triphenylamine derivative is one of the multifunctional materials which has attracted considerable interest of research for their unique radical properties containing triphenylamine unit with higher holes mobility, excellent photoelectric conversion capability. The three benzyl rings of triphenylamine unit can connect different functional groups which can display different activity in the fields of organic solar cells, electroluminescence, electrochromism, optical limiting and chemical sensors. Moreover， the developing prospects of triphenylamine derivative are also briefly discussed.
