Large-bandgap organic semiconductors with trap-free charge transport

Nature Materials, Published online: 29 August 2023; doi:10.1038/s41563-023-01621-1

By optimizing the molecular organization of blue-emitting organic semiconductors, the vulnerability of the materials to extrinsic impurities that cause charge trapping, such as oxygen and water, is strongly reduced. Steric shielding of the electron-transporting core is shown to increase the electron transport by several orders of magnitude.Nature Materials, Published online: 29 August 2023; doi:10.1038/s41563-023-01621-1By optimizing the molecular organization of blue-emitting organic semiconductors, the vulnerability of the materials to extrinsic impurities that cause charge trapping, such as oxygen and water, is strongly reduced.
