红外染料可用于光学记录和光学数据储存,因此它是近年来发展的高技术领域之一。但是目前能应用的红外染料非常少,且绝大部份是菁染料。最近有人报道了醌型和偶氮型红外染料的合成。所谓红外染料是指λ_(man)在700nm以上的分子,含一个发色团体系往往是不够的。因此研究各类助色团和发色 Infrared dyes can be used for optical recording and optical data storage, so it is one of the high-tech areas developed in recent years. However, there are very few infrared dyes that can be used at present, and the vast majority are cyanine dyes. Recently, the synthesis of quinone and azo-type infrared dyes has been reported. The so-called infrared dye refers to the man in the 700nm above molecules, with a chromophore system is often not enough. Therefore, various types of research groups and hair color
