A series of cationic heteroleptic iridium(III) complexes bearing tris-diimine ligands [Ir(phen)2(R-phen)]3+ (R-phen = phenanthroline (1), 3,8-diphenylphenanthroline (2), 3,8-dipyrenylphenanthroline (3), 3-phenylphenanthroline (4), 3-pyrenylphenanthroline (5), and 3,8-diphenylethynylphenanthroline (6)) were synthesized characterized. These possessed phen ligand-localized 1π,π* transitions below 300 nm, charge transfer (1CT) and/or between 520 nm. In 1, 2, 4, 6, the low-energy bands mixed...
Abstract Obtaining homochirality from biased symmetry‐breaking of self‐assembly in achiral molecules remains a great challenge due to the lack ingenious strategies and controlling their handedness. Here, we report first case symmetry breaking platinum (II) liquid crystals which self‐organize into an enantiomerically enriched single domain without selection handedness twist grain boundary TGB [ * ] phase. Most importantly, chiral control self‐organization can be achieved by using above...
Supported palladium sulfide catalysts are of great interest in selective hydrogenation reactions. In this work, "Pd4S", "Pd3S", "Pd16S7" and "PdS" supported on activated carbon were selectively synthesized by tailoring the H2-assisted sulfidation Pd/C with H2S at 150–750 °C, characterized means XRD, XPS, TEM, HRTEM, EDS, BET H2-TPR techniques. The results indicated that atmosphere, temperature metal–support interaction all played important roles determining crystal structure composition...
The major causes of mortality among patients who survive acute lung injury/ARDS (ALI/ARDS) are due to the extensive tissue remodelling and fibrosis. Use high-dose glucocorticoids reduce these inflammatory fibroproliferative responses has been shown do more harm than good. Recently, Meduri et al. found that early use low-dose prolonged methylprednisolone in with severe ALI/ARDS significantly relieved systemic response improved pulmonary extrapulmonary organ function. This study investigated...
A series of Roussin's red salt esters [Fe(2)(micro-RS)(2)(NO)(4)] (R = n-Pr (), t-Bu 6-methyl-2-pyridyl () and 4,6-dimethyl-2-pyrimidyl ()) were synthesized by the reaction Fe(NO)(2)(CO)(2) with thiols or thiolates. Complexes characterized IR, UV-vis, (1)H-NMR, electrochemistry, single-crystal X-ray diffraction analysis. The IR spectra complexes display one weak two strong NO stretching frequencies (nu(NO)) in solution, but only nu(NO) solid. Density functional theoretical (DFT) calculations...
Abstract Water‐soluble 9,10‐diphenylanthracene‐modified γ‐cyclodextrin derivatives A1 and A2 , in which the unit serves as a molecular host for binding sensitizer, 9,10‐diphenylanthracene moiety plays role an emitter/annihilator, were synthesized to investigate supramolecular triplet–triplet annihilation (TTA) upconversion aqueous solution. Both readily aggregate form nanoscale assemblies water combined result of host–guest complexation π–π stacking among 9,10‐diphenylanthracenes. The...
Abstract Several γ‐cyclodextrin (CD) derivatives mono‐ or di‐substituted by pyrenes at the primary rim of CD were demonstrated to aggregate into nano‐strips in aqueous solutions, with pyrene moieties interpenetrating γ‐CD cavities. The hydrophobic complexation‐induced aggregation provides a rigid chiral environment for and leads significant electronic circular dichroism (ECD) circularly polarized luminescence (CPL) activities, giving unprecedently high g abs lum values up 4.3×10 −2 5.3×10 ,...
Abstract A highly selective assay method has been developed to detect mercury (II) (Hg 2+ ) ions using cationic conjugated polymer (CCP). The transduction mechanism is based on a Hg promoted reaction. In the absence of ions, CCP can form complex with an anionic 1,3‐dithiole‐2‐thione derivative through electrostatic interactions. fluorescence efficiently quenched by via electron transfer process. Upon adding transformation into 1,3‐dithiole‐2‐one inhibits quenching, and recovered....

Although much promising synthetic progress in conjugated polymer-based organic solar cells (OSCs) has resulted significant improvement power conversion efficiencies (PCEs) of from over 15 to >19.0% the last five years, sophisticated and complex reactions at least two families’ monomers with remarkably different electron push–pull effects could still pose an unavoidable material burden for commercialization OSCs coming future. Therefore, method preparing a homopolymer sole monomer would...
