摘要：

喷水无墨打印概念的提出对于改善环境污染、资源消耗等问题做出了突出贡献,然而已有的水致变色染料种类较少且开发困难。 本文通过对荧烷化合物(9-(2-羧基苯基)-3,6-双(二乙氨基)占吨翁氯化物,罗丹明B)开关单元进行调控,从而调节分子开关环的动态平衡,实现了酸致变色染料到水致变色染料的调节,并展现了其在喷水无墨打印方面的应用。 该荧烷衍生物水致变色染料的合成可以直接以市售的荧烷化合物为原料,通过两步反应简单修饰,得到的染料摩尔吸光系数达到1×105,所制备的打印纸水写前后反射率变化50%,有望大规模应用到喷水无墨打印中。

Abstract:

The concept of water-jet printing has made a great contribution to the reduction of environmental pollution and resource consumption. However, there are few hydrochromic dyes and they are difficult to develop. Therefore, in order to realize the adjustment of acidochromic dyes to hydrochromic dyes, we adjust the dynamic balance of the switch-ring in molecules by changing the switch units of fluoranes. Fluoranes are synthesized directly from commercial raw materials in two steps and have a high molar absorption coefficient up to 1×105. The reflectivity changes 50% before and after writing with water, which makes it possible to apply widely in water-jet printing.

Key words: hydrochromic, rhodamine, water-jet printing, rewritable
