Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Bipyridine-Directed Syntheses of Uranyl Compounds Containing Semirigid Dicarboxylate Linkers: Diversity and Consistency in Uranyl Speciation, the main research direction is uranyl phenylsulfonecarboxylate pyridine complex preparation photoluminescence; crystal structure uranyl phenylsulfonecarboxylate pyridine.COA of Formula: C12H12N2.
Bipyridine organic bases are beneficial to the synthesis of novel uranyl-organic hybrid materials, but the relationship between their mol. structures and specific roles as structure-directing agents, especially for the semirigid dicarboxylate systems, is still unclear. Here we demonstrate how the bipyridine ligands direct the coordination assembly of uranyl-organic compounds with a semirigid dicarboxylate linker, 4,4′-dicarboxybiphenyl sulfone (H2dbsf), by utilizing a series of bipyridine ligands, 1,10-phenanthroline (phen), 2,2′-bipyridine (2,2′-bpy), 5,5′-dimethylbipyridine (5,5′-dmbpy), 4,4′-bipyridine (4,4′-bpy), or 1,3-di(4-pyridyl)propane (bpp). Under hydrothermal conditions, eight uranyl-organic coordination polymers (UCPs), four of which [[UO2(dbsf)(phen)] (1), [UO2(dbsf)(phen)]·H2O (1′), [U4O10(dbsf)3]2[H2bpp]2 (6), and [U4O10(dbsf)3]2[H2bpp] (6′)] were reported previously, were synthesized and divided into two types based on the chelate or template effect of these bipyridine ligands. 1, 1′, [UO2(dbsf)(2,2′-bpy)] (2), and [(UO2)2(dbsf)2(5,5′-dmbpy)2] (3) are springlike triple helixes with bipyridine ligands (phen, 2,2′-bpy, or 5,5′-dmbpy) as chelate ligands, while [U4O10(dbsf)3][H2(4,4′-bpy)] (4), [U4O10(dbsf)3]2[H(4,4′-bpy)]2[Ni(H2O)6] (5), 6, and 6′ are tetranuclear uranyl-mediated 2-fold-interpenetrating networks with 4,4′-bpy or bpp as template ligands and charge-balancing agents. The participation or not in uranyl coordination of different bipyridine ligands promotes not only diversity in uranyl speciation and final topol. structures among different classes of organic bases but also consistency for the same types of bipyridine ligands, which thus endows the possibility of the rational design of UCPs based on semirigid dicarboxylate ligands with the aid of cautiously selected bipyridine ligands.
This literature about this compound(1762-34-1)COA of Formula: C12H12N2has given us a lot of inspiration, and I hope that the research on this compound(5,5′-Dimethyl-2,2′-bipyridine) can be further advanced. Maybe we can get more compounds in a similar way.
