DNA-CTMA Fluorescent inkjet ink
1 Introduction In recent years, the Eu luminescent materials become one of the key materials for information display and high efficient lighting because of its narrow spectral bands, high purity, good conversion efficiency and stability [1]. Eu luminescent materials showed widely application in the fields of luminescence, optical information transmission, solar photovoltaic conversion, X-ray image and laser [2, 3].

DNA, which has the stable double helix molecular chain structure is the genetic material of organism, carrying and expressing genetic information, which plays a decisive role in the life phenomenon [4]. In recent years, the research of molecular devices based on the interaction of fluorescent dyes with DNA has attracted wide attention. However, DNA is a negatively charged polyamine, and each nucleotide with a negative charge. Nowadays, a lot of research showed that, DNA with positively charged surfactants such as hexadecyltrimethyl-ammonium bromide, CTMA occurs ion exchange reaction, formation of DNA-CTMA cationic surfactants which insoluble in water but soluble in organic solvent such as butanol. In this chapter, the preparation process of Eu(TTA)3(H2O)2 complex and DNA-CTMA compound was reported. The absorption and fluorescence properties of Eu(TTA)3(H2O)2 solution with different concentrations were studied, and the interaction between Eu complex and DNA-CTMA has been analyzed. And the inkjet ink sample was prepared through using Eu(TTA)3(H2O)2 complex doped with DNA-CTMA as the fluorescent dye.
2 Experimental 2.1
Materials
DNA, derived from salmon fish, purchased from Japan. CTMA and Hexadecyltrimethyl-ammonium bromide purchased from TCI Company. Europium (III) acetate hydrate, 2-Thenoyltrifluoroacetone and mineral spirits purchased from TCI Company.
2.2
Instruments
The solution was prepared through using the MS-H magnetic mixer. Vacuum drying oven used to dry the DNA-CTMA complex. UV-Vis absorption spectral was measured using 2501PC UV-Vis spectrophotometer. Emission spectral was measured using RF-5301PC fluorescence spectrometer.
2.3
Preparation of DNA-CTMA
DNA and CTMA dissolved in ultrapure water and stirred about 30 min through using magnetic stirrer, respectively. Then both the solution were mixed and stirred for about 20 min, the resulting solid was filtered and dried for 24 h to obtain the DNA-CTMA compound. The compound dissolved in the n-butyl alcohol, and then, with a magnetic mixer for about 5–6 h, until the DNA-CTM
