The challenges for stretchable organic light‐emitting diodes (SOLEDs) have led research into advanced manufacturing processes. Several electrodes have been researched to replace conventional indium tin oxide in SOLEDs due to its brittleness, indium scarcity in earth, and poor deformation capabilities. Oxide–metal–oxide (OMO) electrodes are promising alternatives for flexible/stretchable electronics owing their excellent charge injection and optical transparencies, including mechanical compliance. In this study, two oxides (i.e., MoO3 and V2O5) with different surface energies in an OMO structure to effectively inhibit the island growth of the ultra‐thin Au (5 nm) metal is incorporated. The morphology and interfacial coordinate covalent bonds between the seed layer and ultra‐thin Au film are extensively studied. The improved ultra‐thin Au growth in OMO structure together with figure‐of‐merit have been employed as the anode for a phosphorescent SOLED structure. The SOLEDs with OMO electrode under V2O5 as bottom oxide remain stable after peeling‐off and sustain a >50% uniaxial strain with a negligible reduction in luminance and current efficiencies. The surface energy and interface of the bottom oxide in the OMO structure are crucial for thin metals to attain superior optical, structural, electronic, and mechanical stability in SOLEDs.

Organic optoelectronic devices have received appreciable attention due to their low cost, mechanical flexibility, band-gap engineering, lightness, and solution processability over a broad area. Specifically, realizing sustainability in organic optoelectronics, especially in solar cells and light-emitting devices, is a crucial milestone in the evolution of green electronics. Recently, the utilization of biological materials has appeared as an efficient means to alter the interfacial properties, and hence improve the performance, lifetime and stability of organic light-emitting diodes (OLEDs). Biological materials can be known as essential renewable bio-resources obtained from plants, animals and microorganisms. The application of biological interfacial materials (BIMs) in OLEDs is still in its early phase compared to the conventional synthetic interfacial materials; however, their fascinating features (such as their eco-friendly nature, biodegradability, easy modification, sustainability, biocompatibility, versatile structures, proton conductivity and rich functional groups) are compelling researchers around the world to construct innovative devices with enhanced efficiency. In this regard, we provide an extensive review of BIMs and their significance in the evolution of next-generation OLED devices. We highlight the electrical and physical properties of different BIMs, and address how such characteristics have been recently exploited to make efficient OLED devices. Biological materials such as ampicillin, deoxyribonucleic acid (DNA), nucleobases (NBs) and lignin derivatives have demonstrated significant potential as hole/electron transport layers as well as hole/electron blocking layers for OLED devices. Biological materials capable of generating a strong interfacial dipole can be considered as a promising prospect for alternative interlayer materials for OLED applications. [ABSTRACT FROM AUTHOR]

Organic light-emitting diodes (OLEDs) perform a vital function in flat-panel displays and solid-state lighting. Herein, a simple structured donor-acceptor based organic light-emitting material (OLEM), 6-(4-(di ([1,1′-biphenyl]-4-yl)amino)phenyl)nicotinonitrile (PTPA-NN), has been prepared and applied as emissive layer in OLEDs. This OLEM has a slightly twisted structure, which enhances its thermal stability. Interestingly, a device consisting of PTPA-NN OLEM demonstrated a promising performance showing a turn-on voltage of 3.8 V with a current efficiency of 9.7 cd/A, external-quantum-efficiency of 4.17% and power efficiency of 8.0 lm/W. Small molecular simple-structured nicotinonitrile based material provide an effective strategy to discover suitable OLEMs for sky-blue OLEDs. • Simple Structure Materials. • Isonicotinonitrile Based Fluorophore. • High Thermal Stability. • Sky Blue Organic Light Emitting Diodes.
