The crystallinity was ranked on a scale of 1 to 10, where 1 was used for samples that did not yield a powder, 2-5 was for samples that were amorphous or had poor crystallinity, while higher numbers were given to powders which presented better crystallinity. Distinctions between 9 and 10 were made for those which presented additional peaks or fully matched the Al-PMOF predicted pattern without any additional phase or impurities, respectively. The ranking from the first generation (Figure ) was used to further optimise the synthesis by generating a second generation of experiments with the genetic algorithm of SyCoFinder (Table ). Again, after synthesis, the PXRD patterns were gathered and the experimental results were ranked. Interestingly, in this second generation, all of the material synthesised proved to be crystalline and matched the PXRD pattern of Al-PMOF (Figure ).
