摘要
在此,我们利用拓扑 DNA 薄膜制造出了发光效率更高、生物相容性更好的有机发光二极管(OLED)。除了 DNA 的天然丰富性和生物兼容性之外,其半柔性的特性还有助于液晶相的出现,从而可以通过施加剪切力形成周期性的波浪起伏结构。由此形成的 "之 "字形结构具有足够的周期性和粗糙度,从而增强了对发射光的有效散射。此外,DNA 涂层红色 OLED 还具有细胞增殖效应,即使在弯曲状态下也表现出很高的电稳定性和热稳定性,这表明它有望应用于基于可附着 OLED 的光疗。
Highly Efficient Organic Light–Emitting Diode Using DNA as Scattering Layer
Herein, an organic light–emitting diode (OLED) is fabricated with increased luminous efficiency and biocompatibility by topographic DNA film. In addition to the natural abundance and biocompatibility of DNA, its semi-flexible characteristics facilitated the emergence of the liquid crystal phase, allowing the formation of a periodic wavy undulation structure by applying shear force. The resultant zigzag structure possesses sufficient periodicity and roughness, enhancing the effective scattering of emitted light. Furthermore, the DNA-coated red OLED demonstrates cell proliferative effects and exhibits high electrical and thermal stability even in a bent state, suggesting its potential application in attachable OLED-based light therapy.
