  photoluminescent and electroluminescent properties of two new Ru(II) complexes described by the general formula [Ru(phen)2X]2+, where phen is 1,10-phenanthroline. The X ligand consists of a 2,2′-bipyridine (bpy) unit substituted with two phenyl rings connected to the bpy core through a saturated (Lhydro = 4,4′-diphenylethyl-2,2′-bipyridine) or a conjugated (LH = 4,4′-bis(α-styrene)-2,2′-bipyridine)

• Synthesis of Halomethyl and Other Bipyridine Derivatives by Reaction of 4,4‘-Bis[(trimethylsilyl)methyl]-2,2‘-bipyridine with Electrophiles in the Presence of Fluoride Ion

  Bipyridine (bpy) ligands figure prominently in many areas of chemistry. Common precursors to many derivatives are the halomethyl-substituted analogues. This report describes a new, high yield route to these valuable compounds via a trimethylsilyl (TMS) intermediate. 4,4'-Dimethyl-2,2'-bpy was reacted with lithium diisopropylamide, and the dianion thus formed was trapped with TMSCl to generate 4,4'-bis[(trimethylsilyl)methyl]-2,2'-bp (1). The TMS group was removed using dry F- sources (TBAF/SiO2 in THF or CsF in DMF) in the presence of BrF2CCF2Br or Cl3CCCl3 to pro duce the bromide 2 or chloride 3 analogues of 4,4'-bis(halomethyl)-2,2'-bipyridine, respectively. The CsF/DMF methodology extends to other electrophiles, including benzaldehyde to give 4,4'-bis(2-hydroxy-2-phenethyl)-2,2'-bpy, 6, as well as to alkyl halides. Benzyl Br, dodecyl Br, and alpha-chloroacetonitrile gave mixtures of di- and monoalkylated products along with the diprotonated product, 4,4'-dimethyl-2,2'-bpy.

  The photophysical and electrochemical properties of cyclometallic cationic iridium complexes that also contain bipyridine type ligands have been investigated in this work. The effect on the photophysical properties of the complexes on the presence of aliphatic long chain or branched substitution was analyzed. The complexes show photoluminescence maxima in the green-blue region of the visible spectrum, with acceptable quantum yields and lifetime, showing in this way potentiality to be tested in OLED devices.
