(DMA) and dimethyl sulfoxide (DMSO); 3. Reaction time, which is the total time our vial was in the microwave (including both: the time required to reach the temperature at which the reaction takes place (< 1 minute) and the reaction time itself); 4. Reaction temperature, the temperature at which the reaction is carried out; 5. Concentration of the reactants, the aluminium to porphyrin ratio was constant and set as in the hydrothermal synthesis. Concentrations 1 and 2 possess the same amount of solvent but different amounts of precursors, while concentrations 2 and 3 possess the same amount of precursors but different volumes (Table ). This systematic approach would allows us to assess the influence of each factor: concentration and pressure in the reaction vial.
