    • The crystal structures of neutral gold bis(1,2-dithiolene) complexes are those with refcodes JEKGAH, XUYLEY, CUCGAJ, CUCGEN, QOYFUG, FQGEO, FOTHUR, TEYSAS, and WUVSAH. The structures POVYOO and SEDLES, which are CT adducts, have not been considered here. CCDC ConQuest version 5.31 updated Feb. 2010

    • With regard to 1, the vertical transition D0âD6 is calculated to occur with an almost negligible oscillator strength (f=0.003). It could be tentatively hypothesized that both the geometry relaxation that occurred during IC processes and the libration of the pyrenyl substituents in solution, which lowers the symmetry of 1, might increase the probability of the transition D6âD0

    • It is acknowledged that electronic transition energy and hyperpolarizability calculations are very sensitive to the basis sets adopted. In particular, diffuse function augmentation can be crucial for small molecules and for high-lying excitation energies (See Ref.[44]). Here, also in consideration of the large number of atoms of the model compounds, the good agreement between the simulated spectra (Figure10) and experimental UV/Vis spectra (Figure1) can be considered an index of the reliability of the level of theory exploited, which has consequently also been adopted for calculating first static hyperpolarizability
