Design and synthesis of non-symmetric phenylpyridine type ligands. Experimental and theoretical studies of their corresponding iridium complexes was written by Iturbe, C.;Loeb, B.;Barrera, M.;Brito, I.;Canete, A.. And the article was included in Polyhedron in 2016.Reference of 4373-61-9 This article mentions the following:
In this work three nonsym. phenylpyridine type ligands, L1, L2 and L3, were designed, and their corresponding Ir complexes, C1, C2 and C3, synthesized, to understand the effect of ligand asymmetry on the properties of the complexes, and to explore their potentiality in light emitting devices. The complexes were structurally characterized by NMR experiments and by x-ray Diffraction, and physicochem. by technics as UV/visible and cyclic voltammetry. Theor. DFT calculations of the energy and electronic d. of the frontier orbitals of the complexes under study were also performed. The energy of the HOMO and LUMO correlated well with the exptl. electrochem. data, and supported the understanding of the processes observed In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Reference of 4373-61-9).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Reference of 4373-61-9
