Pyridinylazolato (N-N') ruthenium(II) complexes of the type [(N-N')RuCl(PMe3)3] have been obtained in high yields by treating the corresponding functionalised azolylpyridines with [RuCl 2(PMe3)4] in the presence of a base. 15N NMR spectroscopy was used to elucidate the electronic influence of the substituents attached to the azolyl ring. The findings are in agreement with slight differences in the bond lengths of the ruthenium complexes. Furthermore, the electronic nature of the azolate moiety modulates the catalytic activity of the ruthenium complexes in the hydrogenation of carbon dioxide under supercritical conditions and in the transfer hydrogenation of acetophenone. DFT calculations were performed to shed light on the mechanism of the hydrogenation of carbon dioxide and to clarify the impact of the electronic nature of the pyridinylazolate ligands. Copyright

We have focused our research on development of the iridium complexes, especially with respect to blue and red emission for OLED. Previously, we prepared bis-[2,3-bis(4-fluorophenyl)quinoxalinato]iridium(acetylacetonate) [Ir(2,3-dpqx-F2)2/
Cationic iridium dendrimers: Synthesis and photophysical properties

Two dendrimers, D1 and D2, containing the cationic iridium complexes (C1 and C2) as cores and truxene-functionalized chromophores as the branches, have been developed by a convergent synthetic strategy. The cationic complexes employ 3-(pyridin-2-yl)-1H-1,

A series of bis(2,2-bipyridyl)ruthenium compounds with pyridin-2-yl-1,2,4-triazoles has been prepared and characterised by their 1H and 13C n.m.r. spectra and their electronic and electrochemical properties.The 1H n.m.r. spectra have been used to ascertain the co-ordination mode of the ligands.The ligands bind in a bidentate fashion and they have ?-acceptor properties that are weaker than 2,2'-bipyridyl (bipy).The excited-state properties of the complexes are similar to those of 2+ but important variations in the energies of the absorption and the emission maxima are observed.

Treatment of N-(2'-aminobenzoyl)-2-pyrydilamidrazone (1) with ethoxymethylenemalononitrile (EMNN) and ethyl ethoxymethylenecyanoacetate (EMCA) or ortho esters afforded the corresponding N-(2'-alkyl-4'-quinazolon-3'-yl)-2-pyridinecarboxamides (2).Furthermore, treatment of 2 with ethanolic hydrochloric acid caused the ring transformation to give corresponding 5-alkyl-3-(2'-pyridyl)-1H-1,2,4-triazoles (3).
