Luminescent Properties of Rhodamine 6G Doped with DNA-CTMA and Its Application in Fluorescent Ink-Jet Ink

In recent years, the research of molecular devices, fluorescent labels and fluorescent probes based on the interaction between biological molecules DNA and fluorescent dyes has aroused widespread concern and attention. This chapter discussed the luminescent properties of fluorescent dye Rhodamine 6G doped with DNA-CTMA lipid complexes. By testing the absorption spectrum and fluorescence spectrum, the effect of DNA-CTMA lipid complexes on the optical properties of dye Rhodamine has been studied, and the emitting mechanism based on the molecular structure has been analyzed. In addition, the luminance ink-jet ink was prepared through using the Rhodamine dye doped with DNA-CTMA as the fluorescent dye, and the ink sample showed good printability and security performance.
