With the goal to provide organometallic triplet emitters with good hole-injection/hole-transporting properties, highly amorphous character for simple solution-processed organic light-emitting diodes, and negligible triplet-triplet (T-T) annihilation, a series of new phosphorescent cyclometalated IrIII and PtII complexes with triphenylamine-anchored fluorenylpyridine dendritic ligands were synthesized and characterized. The photophysical, thermal, electrochemical and electroluminescent properties of these molecules are reported. The incorporation of two sterically hindered electron-rich triphenylamino groups to the 9-position of the fluorene skeleton was found not only to afford triplet emitters in the glassy state with high Tg, but also to elevate the HOMO levels and confer the hole-injection ability to the phosphorescent center. These highly amorphous metal phosphors can serve as doped emitters in a small molecular host for spin-coated emission layer in suitable OLED structures to achieve good device performance with a maximum luminance of 29380 cd m -2 at 23 V, a peak external quantum efficiency of 7.0%, a luminance efficiency of 21.4 cd A-1 and a power efficiency of 2.9 lm W -1. Both the electrophosphorescent device characterization as well as the theoretical simulation results show that these iridium electrophosphors show negligible T-T annihilation even at high operating current densities and moderately high doping levels. Our investigations indicate that attaching the triphenylamino moieties to the fluorene ring is an effective way to overcome the T-T annihilation caused by the strong interactions among the emitting molecules.

Photolysis of ethyl 2-(isoquinolin-1-yl)-3-methyl-5-oxo-2,5-dihydroisoxazole-4-carboxylate occurs by two pathways.The major pathway involves the loss of CO2 to form an imino carbene which may cyclize to form the expected (6) or rearranged (8) imidazo<2,1-a>isoquinolines or react with nucleophiles and recyclize to form the 4-oxopyrimido<2,1-a>isoquinolines.The minor pathway involves electrocyclic ring opening of the isoxazolone and ring closure with or without loss of CO.Pyrolysis leads predominantly to an imino carbene which reacts intramolecularly to give (6) or undergoes insertion into CH bonds.

Application of 19493-44-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.19493-44-8, Name is 1-Chloroisoquinoline, molecular formula is C9H6ClN.

The kinetics of the oxidative additions of haloheteroarenes HetX (X=I, Br, Cl) to [Pd0(PPh3)2] (generated from [Pd0(PPh3)4]) have been investigated in THF and DMF and the rate constants have been determined. In contrast to the generally accepted concerted mechanism, Hammett plots obtained for substituted 2-halopyridines and solvent effects reveal a reaction mechanism dependent on the halide X of HetX: an unprecedented SNAr-type mechanism for X=Br or Cl and a classical concerted mechanism for X=I. These results are supported by DFT studies.

A novel protocol for the preparation of various diarylphosphine oxide compounds via a Ni-catalyzed cross-coupling of aryl chlorides with R 2P(O)H has been developed. Notably, this process exhibits the following very attractive features: (i) the process is simpler and operates under mild reaction conditions; (ii) the process is generally cheaper in part because the more accessible aryl chloride is used to form the C-P bond; (iii) the process avoids the need for simultaneous preparation and use of Ar 2P(O)M.
