In 2017,Van Raden, Jeff M.; Louie, Shayan; Zakharov, Lev N.; Jasti, Ramesh published 《2,2′-Bipyridyl-Embedded Cycloparaphenylenes as a General Strategy To Investigate Nanohoop-Based Coordination Complexes》.Journal of the American Chemical Society published the findings.SDS of cas: 53939-30-3 The information in the text is summarized as follows:
Because of their unique cyclic architectures, tunable electronic properties, and supramol. chemistries, cycloparaphenylenes (CPPs) have the potential to act as a new class of ligands for coordination cages, metal-organic frameworks, and small-mol. transition-metal complexes. However, currently there is no general strategy to coordinate the cyclic framework to a variety of metal centers. The authors report here a general and scalable synthetic strategy to embed 2,2′-bipyridine units into the backbone of CPPs. The authors use this approach to synthesize a 2,2′-bipyridine-embedded [8]CPP (L), which the authors show can successfully coordinate to both Pd(II) and Ru(II) forming [PdLCl2], [PdL2](BF4)2 and [Ru(L)(bipy)2](PF6)2. The resulting coordination complexes, a Pd(II) nanohoop dimer and a bis(bipyridyl)ruthenium(II) functionalized nanohoop, show unique solid-state and photophys. properties. This work provides a proof of concept for a general strategy to use nanohoops and their derivatives as a new class of ligands. The experimental part of the paper was very detailed, including the reaction process of 5-Bromo-2-chloropyridine(cas: 53939-30-3SDS of cas: 53939-30-3)
5-Bromo-2-chloropyridine(cas: 53939-30-3) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. SDS of cas: 53939-30-3
