Something new under the sun

Charge-transfer emission of any type is extremely rare for coordination complexes of iron. Now, an Fe(iii) complex has been devised that shows two-colour luminescence arising from dual metal-to-ligand and ligand-to-metal charge-transfer emission.

Automated summary

Charge-transfer emission, which is rare for iron coordination complexes, has been observed in an Fe(iii) complex. The emission arises from both metal-to-ligand and ligand-to-metal charge transfer.
