Cover Story: This work investigates, from a theoretical point of view, the photophysical properties of two classes of porphyrins and metalloporphyrins combined with N-heterocyclic carbenes (NHC) Au(I) complexes for their use in PDT, evaluating the effect of the presence of both Au(I) and central Zn(II) as well as Pd(II) ions. The outcomes show that the investigated compounds are able to act as photosensitizers in Type II PDT processes as they possess the required photophysical properties. A detailed analysis of the computed spin–orbit coupling constants reveals that the heavy-atom effect, which might increase the probability of the intersystem crossing, is significant only when a Pd(II) ion is present. Moreover, no synergistic effect is detected when a Au(I) ion is contemporaneously present with Zn(II) and Pd(II) ions. View this paper
