Abstract

The salmon sperm DNA is not soluble in any of the organic solvent. Therefore, we modified the structure of natural DNA and changed its solubility. The organic soluble DNA-CTMA was obtained by precipitating the DNA in water with a cationic surfactant such as a lipid of cetyltrimethylammonium chloride (CTMA). The resulting DNA-lipid complex shows good solubility in alcohol and allows us to fabricate thin films for studying their optical and photophysical properties in a solid state. The absorption and photoluminescence (PL) behaviors of DNA-CTMA and CTMA- polyacrylic acid (PA) doped with (E)-2-(2-(4- (diethylamino)styryl)-4H-pyran-4-ylidene)malononitrile (DCM) were studied. We observed the different absorption and PL spectral behaviors with the contents of DCM in two different host materials. This was explained by a proper mechanism based on intercalation or groove binding of fluorescent dye into the base pairs of DNA-CTMA.
