Synthesis, Characterization, and Photophysical and Emission Solvatochromic Study of Rhenium(I) Tetra(isocyano) Diimine Complexes Chi-Chiu Ko Jacky Wai-Kit Siu Apple Wai-Yi Cheung Shek-Man Yiu 10.1021/om200074t.s002 https://acs.figshare.com/articles/dataset/Synthesis_Characterization_and_Photophysical_and_Emission_Solvatochromic_Study_of_Rhenium_I_Tetra_isocyano_Diimine_Complexes/2649541 A new series of rhenium(I) tetra(isocyano) diimine complexes ([Re(CNR)<sub>4</sub>(N–N)]<sup>+</sup>, where R = 4-IC<sub>6</sub>H<sub>4</sub>, 4-BrC<sub>6</sub>H<sub>4</sub>, 4-Br-2,6-Me<sub>2</sub>C<sub>6</sub>H<sub>2</sub>, 2,4,6-Cl<sub>3</sub>C<sub>6</sub>H<sub>2</sub>, 2,4,6-Br<sub>3</sub>C<sub>6</sub>H<sub>2</sub>, 2,4-Cl<sub>2</sub>-6-MeOC<sub>6</sub>H<sub>2</sub> and N–N = bpy, (MeO)<sub>2</sub>bpy, <sup><i>t</i></sup>Bu<sub>2</sub>bpy, phen, 1-methyl-2-(2′-pyridyl)imidazole) with various isocyanide and diimine ligands of diverse electronic and steric natures has been synthesized and characterized. The X-ray crystal structures of four of the target complexes were also determined. These complexes were found to show orange to red MLCT (dπ(Re) → π*(N–N)) phosphorescence. Given the submicrosecond solution emission lifetime, nanosecond transient absorption spectroscopic studies have been performed. The emission solvatochromic behavior and the electrochemical properties of these complexes and their structural correlation have also been reported. 2011-05-23 00:00:00 Br target complexes electrochemical properties Cl 3C Emission Solvatochromic Study emission solvatochromic behavior IC steric natures 6H MLCT diimine ligands submicrosecond solution emission lifetime absorption spectroscopic studies
