Singlet harvesting copper-based emitters: a modular approach towards next-generation OLED technology

Abstract

Copper(I)-based emitters show great potential for addressing the challenges of current organic light-emitting diode (OLED) technology. They can match current state-of-the-art phosphorescent materials for efficiency and can be tuned in color from red to blue. This paper gives an overview, describing examples of mono- and dinuclear Cu(I) complexes in terms of structures and properties. In particular, the modular structure of dinuclear compounds allows the independent tuning of emission color and solubility, making these materials perfect candidates for large area OLEDs produced from solution.
