(3, 4, 5-tmphtpy) 2] Cl 3 (2)[Ru (L 2)], and [Ru (4-thptpy) 2] Cl 3 (3)[Ru (L 3)],(where L= terpy=
2.2′: 6′ 2 ″terpyridine ligands) are synthesized. The complexes were characterized by
elemental analyses, spectroscopic and electrochemical data. The density functional theory
(DFT) outlines the geometric optimisation and electronic charge transition of these
complexes. Photophysical studies describe that the luminescence of Ru (III) complexes is …
