Based on the range of the variables given in Table , we used the SyCoFinder 40 to generate a set of 25 most diverse experiments (Table ). In the first generation, variables are weighted based on the chemical intuition from the solvothermal synthesis, as listed in Table . The type of solvent (i.e., boiling point) was deemed to be the most important variable. Reaction temperature, time and concentration were thought to play a slightly less important role, and power the least important of all the variables studied. These 25 reactions were carried out utilising the microwave and robotic platform (Figure ). After synthesis, each sample was collected individually by centrifugation, washed with the organic solvent used for the reaction itself and then dried overnight in a ventilated oven at 60 • C.
