Description We synthesized the BODIPY-Ru(II) dipyrrin complex in decent yield by reacting beta-dipyrromethanyl substituted BODIPY with [{(eta 6-C10H14)RuCl(mu-Cl)}(2)] under simple reaction conditions. The BODIPY-Ru(II) dipyrrin complex was characterized by 1D, 2D, C-13, B-11, F-19 NMR, HR-MS, UV-vis, fluorescence and electrochemical techniques. The BODIPY-Ru(II) dipyrrin complex was further characterized by X-ray structure analysis, which showed that the Ru(II)-dipyrrin complex is in perpendicular orientation to the BODIPY plane in the BODIPY-Ru(II) dipyrrin complex. The ruthenium metal ion in the BODIPY-Ru(II) dipyrrin complex is bonded to dipyrrin nitrogens, one chloro group and arene ring (arene = C10H14) in an eta(6) manner resulting in a hexa coordination geometry around the Ru(II) ion. The absorption and steady-state fluorescence spectra of the BODIPY-Ru(II) dipyrrin complex showed a broad and hypsochromically shifted absorption and emission bands compared to that of beta-dipyrromethanyl substituted BODIPY. The electrochemical studies indicated that the BODIPYRu(II) dipyrrin complex was easy to reduce compared to beta-dipyrromethanyl substituted BODIPY supporting the electron deficient nature of the BODIPY-Ru(II) dipyrrin complex.
