Self-Assembled Supramolecular Films Derived from Marine Deoxyribonucleic Acid (DNA)−Cationic Surfactant Complexes:  Large-Scale Preparation and Optical and Thermal Properties

Abstract: Series of polyelectrolyte−surfactant complexes, DNA−cationic surfactant complexes (cetyltrimethylammonium, cetylpyridinium, and cetylbenzyldimethylammonium), and their self-assembled bulk film materials were prepared on a large scale. Circular dichroism (CD) analysis indicated that the right-handed double helix structure of DNA was retained in these bulk film materials. TGA analysis suggested that 4 molecules of water were required to retain the B-type conformation of the DNA helix in the self-assembled bulk f… Show more

“…This allows the formation of thin films by casting or spin coating. We have utilized the reaction 9 with cetyltrimethylammonium ͑CTMA͒ to form a DNA-CTMA complex from which thin films were produced. This process has been utilized in investigations of DNA-CTMA as an electro-optical material.…”

“…The term 'conformational gating' 21,22 was coined by Barton's group to describe this phenomenon. Figure 2 compares the electronic spectra of three different DNA À Q þ compositions 19 with that of natural DNA or DNA À Na þ , both in solution and in solid form. Although the details of their absorption spectra are not the same, their absorption positions are more or less similar.…”
