Published: June 2014

A new luminescent platinum(II) complex with phosphinine co-ligands has been discovered.
This complex shows long-lasting light emission when cooled to 77 K (about -196°C).
The cause of this luminescence is linked to a specific excited state associated with the phosphinine, supported by electrochemical and theoretical calculations.

The first luminescent cyclometallated platinum(II) complex bearing phosphinine co-ligands is reported. The long-lived luminescence, which it displays at 77 K, is assigned to a phosphinine-localised triplet excited state on the basis of electrochemical data and TD-DFT calculations.
