Tetraazaporphyrin (TAP) complexes with group 15 elements (phosphorus(V) or arsenic(V)) containing two axial OH ligands showed reversible spectroscopic changes with acid or base doping. Spectroscopic and theoretical analysis revealed that the modification of axial ligands can tune the interaction between peripheral substituents and the TAP macrocycle.
