Merging Platinahelicene and Nanographene: A Strategy for Circularly Polarized Phosphorescence in the Near-Infrared (NIR)

Key Points

• The aim is to combine platinahelicene with nanographene to enable near-infrared phosphorescence.
• Synthesis of platinahelicene and nanographene structures.
• Characterization of phosphorescence properties.
• Measurement of dissymmetry factors.
• Achievement of circularly polarized phosphorescence in the near-infrared range.
• Dissymmetry factors glum reached 4 x 10 –3, demonstrating significant optical activity.
