2,2′-Biquinoline（Cat No.:M067929）is a bidentate heteroaromatic ligand composed of two quinoline units linked at their 2-positions. This rigid, planar structure allows it to coordinate metal centers through its nitrogen atoms, forming stable chelate complexes. It is widely used in coordination chemistry, organometallic catalysis, and materials science, particularly in the development of luminescent complexes and transition metal catalysts. 2,2′-Biquinoline’s extended π-conjugation also imparts interesting photophysical and electrochemical properties, making it valuable in applications such as sensing, light-emitting devices, and the design of functional coordination polymers or supramolecular architectures.
