A series of pure-blue-light emitting Cu(i) complexes with thermally activated delayed fluorescence: structural, photophysical, and computational studies.

Four mononuclear Cu(i)-halide complexes containing phosphines and pyridine ligands with strong electron donor substituents, [CuCl(PPh)(4-NMepy)] (1), [CuI(PPh)(4-NHpy)] (2), [CuI(POP)(4-NHpy)] (3), and [CuI(POP)(4-NMepy)]·0.5(EtO) (4), (PPh = triphenylphosphine, 4-NMepy = 4-(dimethylamino)pyridine, POP = bis[(2-diphenyl-phosphino)phenyl]ether, 4-NHpy = 4-aminopyridine, EtO = diethyl ether) were synthesized and studied with regard to their structural, photophysical properties and theoretical calculations. The complexes exhibit pure blue thermally activated delayed fluorescence (λ = 442 (1), 436 (2), 464 (3), and 448 nm (4)) in crystalline at room temperature.

A two-dimensional silver(I) coordination polymer constructed from 4-aminophenylarsonate and triphenylphosphane: poly[[(μ₃-4-aminophenylarsonato-κ³N:O:O)(triphenylphosphane-κP)silver(I)] monohydrate].

The title compound, {[Ag(C6H7AsNO3)(C18H15P)]·H2O}n, has been synthesized from the reaction of 4-aminophenylarsonic acid with silver nitrate, in aqueous ammonia, with the addition of triphenylphosphane (PPh3). The Ag(I) centre is four-coordinated by one amino N atom, one PPh3 P atom and two arsonate O atoms, forming a severely distorted [AgNPO2] tetrahedron. Two Ag(I)-centred tetrahedra are held together to produce a dinuclear [Ag2O2N2P2] unit by sharing an O-O edge.

A three-dimensional coordination polymer based on the Zn₄(μ₃-OH)₂ unit: poly[[(μ₄-benzene-1,4-dicarboxylato)bis(μ₃-benzene-1,4-dicarboxylato)bis(μ₃-hydroxido)bis(1,10-phenanthroline-5,6-dione)tetrazinc] dihydrate].

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2 fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron.

Predictors of liver failure in primary biliary cirrhosis.

Background: The disease progression of patients with primary biliary cirrhosis (PBC) varies significantly, and the prognostic markers that identify those patients who will develop liver failure have been scarcely studied from a Chinese cohort. Aims. We aimed to determine the predictive factors of liver failure in patients with PBC.

Acute liver failure caused by severe acute hepatitis B: a case series from a multi-center investigation.

Background: Few data can be available regarding acute liver failure (ALF) caused by severe acute hepatitis B up to now. This study aims to report such cases from China.

Findings: We conducted a multi-center investigation on ALF from 7 tertiary hospitals in different areas of China.

Acute liver failure in Chinese children: a multicenter investigation.

Background: Currently, no documentation is available regarding Chinese children with acute liver failure (ALF). This study was undertaken to investigate etiologies and outcomes of Chinese children with ALF.

Methods: We retrospectively enrolled 32 pediatric patients with ALF admitted in five hospitals in different areas of China from January 2007 to December 2012.

Omeprazole affects clopidogrel efficacy but not ischemic events in patients with acute coronary syndrome undergoing elective percutaneous coronary intervention.

Background: Omeprazole, usually used in the antiplatelet therapy during percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS), has been reported to increase ischemic events in retrospective studies. However, other clinical trials gave paradoxical results. The aim of this study was to assess the effects of omeprazole on clopidogrel efficacy and clinical events.
