characterization and biological activity of neutral fluorescent Ir(III) and Ru(II) half-sandwich organometallic complexes containing phosphine-sulfonate ligands are reported. X-ray crystal structure of complexes 1–3, 10 and 11 exhibits the expected half-sandwich “three-legged piano-stool” pseudo-octahedral geometry. Spectroscopic properties study displays that these complexes show rich fluorescence properties. With

The present invention relates to linker-drug compounds (LDs) and antibody-drug conjugates (ADCs) comprising a non-linear self-immolative linker, which is cleavable or transformable under appropriate conditions and which reduces the hydrophobicity of the antibody-drug conjugate.

species (TS(10'-11')). Easy chain transfer was suggested to proceed from the more stable PdH(olefin) complex 12' if beta-hydride elimination to 12' does take place. Thus, the production of linear polyethylene with high molecular weight under ethylene pressure suggests that the cis and trans PdH(alkene)(phosphine-sulfonate) complexes (12 and 12') are merely accessible in the presence of excess amount of ethylene

A compound comprising a sulfonated triorganophosphine of formula R1R2PR3[SO3M)]n, wherein R1 and R2 are selected individually from alkyl, aralkyl, and alicyclic groups; wherein R3 represents a branched divalent or polyvalent, alkylene or alicyclic radical that is bonded to the phosphorus atom and to one or more sulfonate substituents, and further wherein R3 does not contain any aryl moieties; M represents a monovalent cation; and n is an integer representing a total number of sulfonated substituents. The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alkyl-aryl exchange, thereby leading to reduced ligand usage and improving ligand and transition metal, e.g., rhodium, recovery and recycling, as compared with prior art ligands.
An luminescent device material which is inexpensive and exhibits excellent durability in the presence of oxygen can be provided using a luminescent silver complex which has an organic multidentate ligand, particularly, a luminescent silver complex wherein the organic multidentate ligand is coordinated to a phosphorus atom, a nitrogen atom, an oxygen atom, a sulfur atom, an arsenic atom, an oxygen anion, a nitrogen anion, or a sulfur anion, or a polymer of the luminescent silver complex.
