Unexpected substituent effects in offset π-π stacked interactions in water
Rashkin, Mark J.,Waters, Marcey L.
, p. 1860 - 1861 (2002)
We have measured the rotational barriers of meta- and para-substituted N-benzyl-2-(2-fluorophenyl)pyridinium bromides in aqueous solution by dynamic NMR as a model system for offset-stacking interactions in proteins. Because the benzyl ring can stack with
Preparation method and application of aggregation-induced emission halogen modified platinum complex

Paragraph 0011; 0026-0028, (2020/12/05)
The invention discloses a preparation method and application of an aggregation-induced emission halogen modified platinum complex, and belongs to the field of phosphorescent materials. According to the invention, seven platinum complexes are synthesized by taking a halogen-modified 2-phenylpyridine derivative as a cyclometalated ligand and 1, 10-phenanthroline as an auxiliary ligand. The method for synthesizing the cyclometalated ligand from the complex through Suzuki cross-coupling reaction is environment-friendly, simple, convenient and efficient. Through modular design, the halogen-modifiedcyclometalated platinum complex can obtain a platinum complex with excellent aggregation-induced emission properties, and has important application value in the field of phosphorescent materials.
Aryl-Fluoride Bond-Forming Reductive Elimination from Nickel(IV) Centers

The treatment of pyridine- and pyrazole-ligated NiII σ-aryl complexes with Selectfluor results in C(sp2)-F bond formation under mild conditions. With appropriate design of supporting ligands, diamagnetic NiIV σ-aryl fluoride intermediates can be detected spectroscopically and/or isolated during these transformations. These studies demonstrate for the first time that NiIV σ-aryl fluoride complexes participate in challenging C(sp2)-F bond-forming reductive elimination to yield aryl fluoride products.
