By judicious ligand design, the quantum yield of the phosphorescence emission from pyridine-2,6-dipyrrolide bismuth complexes increases by up to 20-fold.
New Cu(I) and Ag(I) phosphane complexes supported by β-diketonate ligands were synthesized and evaluated for their antitumor activity by 2D and 3D cell viability studies.
Primary amide complexes TptBu,MeYb(NHR)(thf)x readily engage in donor exchange and YbII/YbIII redox chemistry but seem to be unreactive towards ultimate deprotonation.
Ligand modification in β-thioketiminate copper(I) complexes enhances Cu⋯Cu short contacts, as confirmed by X-ray and Raman analyses.
Permethylation of the phenylene linker in a cationic ferrocenyl-phenylthioxanthylium dyad increases the amount of the diradical ferrocenium thioxanthyl radical valence tautomer and aids in supressing its dimerization.
