Five novel Ru(II) phenanthroline complexes with an addnl. aryl sulfonate ligating substituent at the 5-position were synthesized: [Ru(L)(bpy)2](BF4)2 (1), [Ru(L)(bpy)(SCN)2] (2), [Ru(L)3](BF4)2 (3), [Ru(L)2(bpy)](BF4)2 (4) and [Ru(L)(BPhen)(SCN)2] (5) (L = (6-one-[1,10]phenanthroline-5-ylamino)-3-hydroxynaphthalene-1-sulfonic acid, bpy = 2,2′-bipyridine, BPhen = 4,7-diphenyl-1,10-phenanthroline), as both photosensitizers for oxide semiconductor solar cells (DSSCs) and light emitting diodes (LEDs). The absorption and emission maxima of these complexes red shifted upon extending the conjugation of the phenanthroline ligand. Ru phenanthroline complexes exhibit broad metal to ligand charge transfer-centered electroluminescence (EL) with a maximum near 580 nm. A particular structure (2) can be considered as both DSSC and OLED devices. The efficiency of the LED performance can be tuned by using a range of ligands. Device (2) has a luminance of 550 cd m-2 and maximum efficiency of 0.9 cd A-1 at 18 V, which are the highest values among the 5 devices. The turn-on voltage of this device is ∼5 V. The role of auxiliary ligands in the photophys. properties of Ru complexes was studied by DFT calculation Photovoltaic properties were studied of dye-sensitized nanocrystalline semiconductor solar cells based on Ru phenanthroline complexes and an I redox electrolyte. A solar energy to electricity conversion efficiency (η) of 0.67% was obtained for Ru complex (2) under standard AM 1.5 irradiation with a short-circuit photocurrent d. (Jsc) of 2.46 mA cm-2, an open-circuit photovoltage (Voc) of 0.6 V, and a fill factor (ff) of 40%, which are all among the highest values for Ru sulfonated anchoring groups reported so far. Monochromatic incident photon to current conversion efficiency was 23% at 475 nm. Photovoltaic studies clearly indicated dyes with 2 SCN substituents yielded a higher Jsc for the cell than dyes with a tris-homoleptic anchor substituent.
