Overview

Research uncovers enhanced dual emission capabilities in chiral metal clusters, indicating promise for advanced photonic applications.

Key Points

  • This research aims to improve the circularly polarized luminescence (CPL) properties of chiral metal clusters.
  • Synthesized enantiomeric pairs of homometallic and heterometallic clusters.
  • Stabilized clusters using a bis-thiophosphinate spiro ligand.
  • Examined emission characteristics in both visible and near-infrared regions.
  • Explored guest-induced modulation of ligand flexibility.
  • R/S-Ag 21 showed a | g lum | value of 4.7 × 10 −4.
  • R/S-PtAg 20 exhibited dual emission CPL behavior with | g lum | values of 6.4 × 10 −4 in visible light and 1.3 × 10 −2 in NIR.
  • Identified two independent triplet excited states contributing to luminescence in R/S-PtAg 20.
  • Demonstrated tunable emission modes via modulation of ligand rigidity.
