So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Peterson, Anna; Kaabel, Sandra; Kahn, Iiris; Pehk, Tonis; Aav, Riina; Adamson, Jasper researched the compound: 2,9-Dimethyl-1,10-phenanthroline hemihydrate( cas:34302-69-7 ).Name: 2,9-Dimethyl-1,10-phenanthroline hemihydrate.They published the article 《Unsubstituted Oxacalix[n]arenes (n=4 and 8): A Conformational Study in Solution and Solid State and Interaction Studies with Aromatic Guests》 about this compound( cas:34302-69-7 ) in ChemistrySelect. Keywords: oxacalixarene conformation crystal structure benzoic acid ferrocene inclusion reaction. We’ll tell you more about this compound (cas:34302-69-7).
We present single crystal structures of unsubstituted oxacalix[4]arene and oxacalix[8]arene macrocycles and investigate the weak supramol. interactions that govern their packing in the solid state. We further show that the unsubstituted oxacalix[4]arene shows weak complexation with two aromatic guest species, benzoic acid and ferrocene, in CDCl3, whereas the oxacalix[8]arene host does not complex with these guest mols. We also present NMR titration experiments with non-aromatic acids and DFT calculations that signify the importance of π-π interactions for complexation with benzoic acid. Weak complexation is also observed between electron-rich aromatic guest mols. and the unsubstituted oxacalix[4]arene host.
The article 《Unsubstituted Oxacalix[n]arenes (n=4 and 8): A Conformational Study in Solution and Solid State and Interaction Studies with Aromatic Guests》 also mentions many details about this compound(34302-69-7)Name: 2,9-Dimethyl-1,10-phenanthroline hemihydrate, you can pay attention to it, because details determine success or failure
