We report on fabrication and characterization of polymer light emitting diode by using a thin film of pure deoxyribonucleic acid as electron blocking layer (EBL). A thin film of phosphorescent Ir(ppy) 3 luminophore, embedded in the poly(N-vinylcarbazole) (PVK)/2-(4-tert-butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole (PBD) is used as emission layer. The obtained BioLED shows a good stability and its luminous efficiency isimproved by ca 40% as compared to the case without EBL. The result shows that using the DNA layer one can either improve the OLED brightness at the same current density or operate at a significantly lower current density with the same brightness than without it.

“…Engineered materials from organic compounds have received a large interest so far in order to develop novel photonic devices for a broad range of applications [1][2][3] from sensing to communication devices. In this respect, biomaterials possess an interesting potential, especially in terms of costs, availability and waste.…”

The first hyperpolarizability of the DNA bases Thymine and Cytosine were determined by Hyper Rayleigh Scattering in neat water despite their low solubility. Due to the low intensity levels collected, count statistics was performed instead of the standard dilution procedure. The first hyperpolarizability were found to be 𝛽 = (2.99 ± 0.44) × 10 esu for Thymine and 𝛽 = (3.35 ± 0.21) × 10 esu for Cytosine. Due to its weak solubility, only an upper limit 𝛽 < (1.82 ± 0.10) × 10 esu could be set for Adenine. The first hyperpolarizability of Guanine could not be measured because of its too weak solubility.Theoretical static and 800 nm dynamic first hyperpolarizability tensor elements were also computed with Gaussian 09 for comparison.

“…For instance, DNA extracted from fish industry waste is not yet a commodity for any industry. However, as already shown in several papers it is a promising material that can be used in opto-electronic application [1][2][3] as wave guides [4][5], ionically conducting membranes for electrochemical devices such as electrochromic (ECD) [6], dye sensitized solar cells (DSSC), organic filed-effect transistors (OFET) [7][8] or organic light emitting diodes (OLED) [9].…”

Natural macromolecules are very promising row materials to be used in modern technology including security and defense. They are abundant in nature, easy to extract and possess biocompatibility and biodegradability properties. These materials can be modified throughout chemical or physical processes, and can be doped with lithium and rare earth salts, ionic liquids, organic and inorganic acids. In this communication samples of DNA and modified DNA were doped with Prussian Blue (PB), poly(ethylene dioxythiophene) (PEDOT), europium and erbium triflate and organic dyes such as Nile Blue (NB), Disperse Red 1 (DR1) and Disperse Orange 3 (DO3). The colored or colorless membranes were characterized by electrochemical and spectroscopic measurements, and they were applied in electrochromic devices (ECDs) and dye sensitized solar cells (DSSC). ECDs change the color under applied potential, so they can modulate the intensity of transmitted light of 15 to 35%. As the electrochromic materials, WO 3 or Prussian blue (PB), are usually blue colored, the color change is from transparent to blue. DNA, and the complexes: DNA-CTMA, DNA-DODA and DNA-PEDOT:PSS were also investigated as either hole carrier material (HTM) or polymer electrolyte in dye-sensitized solar cells (DSSC). The DNA-based samples as HTM in small DSSCs revealed a solar energy conversion efficiency of 0.56%. Polymer electrolytes of DNA-CTMA and DNA-DODA, both with 10 wt% of LiI/I 2 , applied in small DSSC, exhibited the efficiencies of 0.18 and 0.66%, respectively. The obtained results show that natural macromolecules-based membranes are not only environmentally friendly but are also promising materials to be investigated for several electrochemical devices. However, to obtain better performances more research is still needed.
