We present a physically intuitive model of molecular quantum dots beyond the constant interaction approximation. It accurately describes their charging behavior and allows the extraction of important molecular properties that are otherwise experimentally inaccessible. The model is applied to data recorded with a noncontact atomic force microscope on three different molecules that act as a quantum dot when attached to the microscope tip. The results are in excellent agreement with first-principles simulations.

Acetate ligand metathesis results in the first hybrid [MIII(Pc)(PW11O39)]6– (M = Y, Dy, Tb) double-decker scaffolds, where a phthalocyanate (Pc2–) and one of the conceptually most simple polyoxotungstates, a monolacunary...
