Key Takeaways

• A research team at Lawrence Berkeley National Laboratory has developed “supramolecular ink,” a new 3D-printable material that could revolutionize the electronic display industry.
• This innovative ink is made of inexpensive, Earth-abundant elements, replacing costly scarce metals, and requiring far less energy to manufacture than conventional methods.
• It has the potential to enhance the sustainability of 3D-printable wearable devices, lighting technologies, and luminescent art and sculpture.

The newly developed “supramolecular ink” technology, created by a team led by Lawrence Berkeley National Laboratory (Berkeley Lab), offers a breakthrough in the field of organic light-emitting diode (OLED) displays and other electronic devices. This 3D-printable material is composed of inexpensive, Earth-abundant elements, making it a cost-effective and environmentally friendly alternative to current manufacturing methods.

This advancement comes from the research of principal investigator Peidong Yang, a senior scientist at Berkeley Lab’s Materials Sciences Division and a professor at UC Berkeley. Yang believes that this supramolecular ink has the potential to transform the OLED display industry and extend its applications to wearable devices, lighting technologies, and artistic creations.

“By replacing precious metals with Earth-abundant materials, our supramolecular ink technology could be a game changer for the OLED display industry.”

– Peidong Yang

One of the key advantages of this new material is its potential to reduce the costs and energy consumption in the manufacturing process of electronic displays. Compared to traditional methods that rely on rare, expensive metals such as iridium, the supramolecular ink offers a more affordable and sustainable alternative.

The material, made of hafnium (Hf) and zirconium (Zr) powders, can be mixed at low temperatures to form a semiconductor “ink.” The ink’s molecular structures self-assemble in solution, enabling stable and high-purity synthesis at low temperatures. These structures have been shown to emit efficient blue and green light, making them suitable for use in energy-efficient OLED emitters.

The potential of the supramolecular ink extends to 3D printing technologies, where it can be used to design decorative OLED lighting and wearable devices that illuminate for safety in low-light conditions. The material also has applications in the creation of high-tech clothing and programmable electronic displays.

The supramolecular ink is not only a testament to the ingenuity of sustainable material development but also a step towards commercializing ionic halide perovskites, a thin-film solar material that has long been of interest to the display industry. With its lead-free formulation and exceptional performance, the supramolecular ink offers a promising alternative to high-performance halide perovskites that contain the element lead, which raises environmental and health concerns.

As the researchers continue to explore the material’s potential in electroluminescent devices, the development of the supramolecular ink opens up new possibilities for efficient light-emitting technologies and sustainable semiconductor manufacturing.

The success of the supramolecular ink technology represents a significant milestone in the pursuit of sustainable and energy-efficient materials for electronic displays and 3D-printable electronics.

With its demonstrated stability and shelf life, the supramolecular ink technology has the potential to reshape the landscape of electronic displays and semiconductor manufacturing, offering a more affordable, environmentally friendly, and efficient alternative to current methods.
