Project description
A breakthrough for stable and efficient blue OLEDs
Modern society relies on digital displays and lighting, making energy efficiency a critical challenge. OLED technology offers a low-energy alternative to traditional lighting and display solutions, but its full potential remains untapped. The biggest hurdle is the instability of the blue emitter, which forces manufacturers to choose between efficiency and longevity. This trade-off leads to either wasted energy or short-lived devices, limiting OLED adoption. Supported by the Marie Skłodowska-Curie Actions programme, the HyperDyad project seeks to overcome this challenge with a breakthrough in molecular design. By tethering two molecules together with a rigid bridge, the project ensures precise control over their orientation and distance, improving energy transfer efficiency. This approach promises to advance energy-efficient technology.
Objective
With an ever-growing population, reducing our demand for energy is a key challenge in building a sustainable future. As part of tackling this problem, Organic Lighting-emitting Diodes (OLEDs) show great potential for application in low-energy consumption displays, lighting, and lasers. OLEDs are increasingly featured in high end consumer electronics; however, their potential is yet to be realised. Undoubtedly, the largest problem OLEDs face today is the instability of the blue emitter. Commercial OLEDs currently employ either an inefficient but stable blue emitter (resulting in energy wastage) or an efficient but unstable blue emitter (resulting in short-lived devices).
By splitting the task of energy conversion and emission between two molecules within a device, stable and efficient blue emission is achievable. However, the current approach is to disperse these two molecules within a host, which leads to unpredictable orientations and distances between molecules. This results in detrimental processes within the device that reduce both efficiency and lifetime. Traditionally thought to be a device engineering problem, I propose a step change in thought. In a new approach to molecule design, I aim to tether the molecules together using a rigid bridging unit, forming a ‘dyad’ which gives precise control over the orientation and distances within a device. I aim to explore the efficiency of energy transfer as a function of the bridging unit to develop a structure-function relationship. The results of this work will establish design criteria for dyads which will facilitate the development of both efficient and stable blue emitters.
