the quinoline ring on the N^Nligand caused red-shifted charge-transfer absorption band and emission band for complexes Ir2, Ir8, Ir10 vs Ir1 and Ir3 vs Ir2, while benzannulation at the 4,5-/4′,5′-position of 2,2′-bipyridine ligand or at the 7,8-position of the quinoline ring on the N^Nligand induced a blue shift of the charge-transfer absorption and emission bands for complex Ir9 vs Ir1 and Ir4 vs Ir2

Several photoactive platinum alpha-diimine intercalators have been prepared to develop new probes of DNA oxidation and reduction chemistry. Five water-soluble bis(mes')Pt(II) complexes (mes' = N,N,N,3,5-pentamethylaniline) with various aromatic alpha-diimine ligands (dppz = dipyridophenazine, np = naphtha[2,3-f][1,omega]phenanthroline, CN-np = naphtho[2,3-f][1,10]phenanthroline-9-carbonitrile, CN(2)-np

An organic light-emitting device includes a substrate, an anode and a cathode disposed over the substrate, and a luminescent layer disposed between the anode and the cathode wherein the luminescent layer includes a host and at least one dopant. The host of the luminescent layer is selected to include a solid organic material comprising a mixture of at least two components, one of which is capable of forming both monomer state and an aggregate state.

A comparative study of [Pd((NC)-C-boolean AND)((NN)-N-boolean AND)](+) complexes ((NC)-C-boolean AND)(-) are deprotonated forms of 2-phenylpyridine and 2-(2-thienyl)pyridine and ((NN)-N-boolean AND) is 1,10-phenantroline, dipyrido[f,h]quinoxaline, dipyrido[a,c]phenazine or 6,7-dicyanodibenzo[f,h]quinoxaline} was carried out by the methods of H-1 NMR, electronic absorption and emission spectroscopy, and cyclic voltammetry. Optical and electrochemical properties of dipyrido-substituted 1,4-diazines are conditioned by the electron transfer involving pi* orbitals localized on weakly interacting phenantroline (pi(*)(phen)) and diazne (pi(*)(diaz)) components.
