3,4,7,8-Tetramethyl-1,10-phenanthroline Chemical Properties,Uses,Production

Description

3,4,7,8-Tetramethyl-1,10-phenanthroline is used as a metal-chelating agent. For instance, it is used in the synthesis of heteroleptic cationic Ir(III) complex: 3,4,7,8-tetramethyl-1,10-phenanthroline-bis[2-(2’,4’-difluorophenyl)pyridine]iridium(III) hexafluorophosphate. It is used as a ligand to form dinuclear Cu(II) hypocrelin B complexes. It also forms tetraaqua(3,4,7,8-tetramethyl-1,10-phenanthroline-kappa2N,N′)zinc(II) thiosulfate complex with zinc.
