다양한 Cyanine Dyes의 합성및 특성에 관한 연구
- Alternative Title
- A study on the synthesis and characterization of various cyanine dyes
- Abstract
- A number of application was highlighted from the studies on the reversible color change and other change in physical and chemical properties of the photochromic polymers. The thermally stable and photostable cyanine dyes of photochromic dyes were synthesized on various chemical chains salt. Most of the research was focused on the potential application of spiropyran-merocyanine systems in optical memories and switches. In this study, we made much effort to increase the stability of the photochromism in this dye system using the cyanine dye groups in the polymer matrix.
The polymer system contains the two compoents that can show photocrosslink and photochromism under UV irradiation respectively. We synthesized three kinds of cyanine dyes with three kind of salt to investigate the stability of photochromism and thermal stable. The kinetic behaviors for the chromism of these polymers were investigated to evalute the photostability which was consifered as the effect of steric hindrance.
