Enhanced emission efficiency in organic light-emitting diodes using deoxyribonucleic acid complex as an electron blocking layer

“…2 intuitively shows that DNA-CTMA will act as an EBL in the device. With a LUMO level 6 of 0.9 eV electrons in the NPB layer will experience an energy barrier of 1.4 eV. The DNA-CTMA HOMO level 6 of 5.6 eV should not inhibit hole transport.…”

“…With a LUMO level 6 of 0.9 eV electrons in the NPB layer will experience an energy barrier of 1.4 eV. The DNA-CTMA HOMO level 6 of 5.6 eV should not inhibit hole transport. Long distance hole transfer has also been reported for DNA in solution.…”

“…Hirata et al have investigated 6 the properties of DNA as a charge transport layer in several device configurations elucidating their properties through their effect on the device current-voltage ͑I-V͒ characteristics.…”

Optical, electro-optic and optoelectronic properties of natural and chemically modified DNAs

“…The devices without the DNA-CTMA layer achieve values of 4500 and 800 cd m À2 , respectively. The fabrication of natural DNA-containing OLEDs was recently described in detail by Gomez et al 57 Earlier, the Japanese group lead by Hirata et al 58 constructed OLED devices containing a DNA-CTMA layer, which they utilized for a study of the electrical properties of the layer. Their conclusion was that the DNA-CTMA layer preferentially transports holes rather than electrons.…”

Challenges and Opportunities for Biophotonic Devices in the Liquid State and the Solid State

“…DNA-based BioLEDs previously reported 5,6 have incorporated DNA-based thin films as hosts for lumophores indicating the feasibility of the concept, but without significant improvement in device performance over conventional OLEDs. Hirata et al have investigated 7 the properties of DNA as a charge transport layer in several device configurations elucidating their properties through their effect on the device current-voltage (I-V) characteristics. Organic light emitting diodes are very bright, efficient, have a relatively low fabrication cost as compared to inorganic LEDs, and have begun to gain momentum in both display and lighting applications.…”
