Doping, Ionic Conductivity and Photothermal Stability of Functionalized DNA for Solar Energy Conversion and Electrochromic Applications

Abstract

Biopolymers DNA and collagen were studied for their practical application in photonics and electronics. They were functionalized with optically active chromophores. Additionally DNACTMA complexes is known for excellent optical properties and solubility in other solvents than water, the only solvent of DNA. Thermal and photodegradation of thin films of two biopolymers and the stability of embedded chromophores were studied at room and elevated (85 deg C) temperatures as well as under UV irradiation. Thin films were obtained by spin coating of corresponding solutions on glass substrates. Fluorescence of active molecules was also studied as a function of matrix and fluorophore concentration. The optical damage threshold for several systems was also determined and it was found to be larger than in synthetic chromophores. Practical application of DNA as a solid polyelectrolyte was demonstrated in electrochromic cell acting as a smart window structure.
