A family of light-emitting gold complexes have been synthesized and their crystalline structures and luminescence properties characterized.
Compounds that emit light in response to external stimuli are used in a wide range of sensors. Luminescent gold(I) complexes with various chemical groups attached are highly promising in this regard.
Now, a Russian team that included a chemist from Peter the Great St. Petersburg Polytechnic University has synthesized a family of gold(I) phosphine alkynyl complexes on a flexible substrate and investigated their luminescence properties.
The researchers found that the crystal structure, and hence the luminescence properties, varied depending on the kind of solvent used in crystallization. Theoretical calculations indicated that the luminescence properties, including the emission wavelength, depend on the rotation of the functional groups on the compounds.
