摘要
概述了一种功能化学材料—有机光致变色材料,它在不同波长光的照射下,通过开环-闭环、结构异构和氧化还原等过程,能够发生颜色的变化。介绍了其在防伪技术领域的一些应用,并提出了一些增加防伪力度的思路。其中光致变色材料的应用,将是防伪技术领域的一个值得重视且亟待深入研究的工作。
A functional chemical materials--organic photochromic materials were outlined. It could change color through the opening ring-the closed ring, structure isomerous and redox process, ect. , in different wavelengths of light irradiation. Some of its anti-counterfeiting applications were introduced. The proposals of increase anti-counterfeiting effects were put forward. Applying organic photochromic materials to develop new anti-counterfeiting materials is worthy to be emphasized and enhanced in the relevant investigations.
