Name: 6H-Benzo[c]chromen-6-one. I found the field of Chemistry very interesting. Saw the article One class classification as a practical approach for accelerating pi-pi co-crystal discovery published in 2021.0, Reprint Addresses Dyer, MS (corresponding author), Univ Liverpool, Dept Chem, 51 Oxford St, Liverpool L7 3NY, Merseyside, England.; Dyer, MS (corresponding author), Univ Liverpool, Mat Innovat Factory, 51 Oxford St, Liverpool L7 3NY, Merseyside, England.; Dyer, MS (corresponding author), Univ Liverpool, Leverhulme Res Ctr Funct Mat Design, Oxford St, Oxford, England.. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one.
The implementation of machine learning models has brought major changes in the decision-making process for materials design. One matter of concern for the data-driven approaches is the lack of negative data from unsuccessful synthetic attempts, which might generate inherently imbalanced datasets. We propose the application of the one-class classification methodology as an effective tool for tackling these limitations on the materials design problems. This is a concept of learning based only on a well-defined class without counter examples. An extensive study on the different one-class classification algorithms is performed until the most appropriate workflow is identified for guiding the discovery of emerging materials belonging to a relatively small class, that being the weakly bound polyaromatic hydrocarbon co-crystals. The two-step approach presented in this study first trains the model using all the known molecular combinations that form this class of co-crystals extracted from the Cambridge Structural Database (1722 molecular combinations), followed by scoring possible yet unknown pairs from the ZINC15 database (21 736 possible molecular combinations). Focusing on the highest-ranking pairs predicted to have higher probability of forming co-crystals, materials discovery can be accelerated by reducing the vast molecular space and directing the synthetic efforts of chemists. Further on, using interpretability techniques a more detailed understanding of the molecular properties causing co-crystallization is sought after. The applicability of the current methodology is demonstrated with the discovery of two novel co-crystals, namely pyrene-6H-benzo[c]chromen-6-one (1) and pyrene-9,10-dicyanoanthracene (2).
