Abstract

This study developed an external magnetic field–driven organic light-emitting diode (OLED) that can emit tunable circularly polarized electroluminescence (CPEL) by incorporating achiral optically inactive phosphorescent organic Pt(II) luminophores in the emission layer. The experimental results showed that in the proposed magnetic circularly polarized OLED (MCP-OLED) system, the luminescent color (luminescent wavelength) of magnetic CPEL (MCPEL) can be controlled by adjusting the concentration of achiral organometallic Pt(II) luminophores in the emission layer. Furthermore, MCPEL inversion was controlled by switching the Faraday geometric configuration of the applied magnetic field.
