Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Photoluminescence: Applications

1.2K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

  • Single-crystal X-ray diffraction for structural elucidation.
  • UV/Vis absorption and photoluminescence (PL) spectroscopy.

Main Results:

  • Seven novel indium complexes were successfully synthesized and characterized.
  • Complexes displayed high stability in air and aqueous solutions.
  • Solid-state structures revealed square-pyramidal geometry around indium.
  • Intramolecular charge transfer (ICT) transitions were observed, leading to tunable emission from 455-622 nm.

Conclusions:

  • The synthesized indium complexes are stable and exhibit tunable photoluminescence.
  • Substituent modifications on the salen ligand effectively control the emission wavelengths.
  • These complexes hold potential for applications in luminescent devices and sensors.
