In this paper we describe experimental evidence of the change in emission energy as a function of gold-gold distance. We have employed a luminescent complex exhibiting an aurophilic interaction, which is weak enough to allow its length to be modified by external pressure, but rigid enough to confer structural stability on the complex. By determining the crystal structures and emission characteristics over a range of pressures, we have identified an exponential relationship between the wavelength of the emitted light and the metal-metal distances under pressure. This result can be indirectly related to the repulsive branch of the fitted function representing the energy of the system at different gold-gold distances. The relativistic nature of gold appears to play an important role in the behaviour of this complex.
