Reagent used for Rhodium-catalyzed intramolecular amination; Pd-catalyzed direct arylation; Mizoroki-Heck and Suzuki-Miyaura coupling reactions catalyzed by palladium nanoparticles; Palladium-catalyzed stereoselective Heck-type reaction; Highly effective Palladium-catalyzed arylation Suzuki-Miyaura cross-coupling in water; Reagent used in Preparation of Ni(II) pincer complex and Pd(II) pyridoxal hydrazone metallacycles as catalysts for the Suzuki-Miyaura cross-coupling reactions; N-type polymers for all-polymer solar cells. It serves as a receptor for carbohydrates, antimicrobial agents and enzyme inhibitors in biological reactions. It is also employed as a sensor for neutron capture therapy for cancer, transmembrane transport and bioconjugation and labeling of proteins and cell surface.
