Oxygen exists in two gaseous (dioxygen and ozone) six solid allotropic modifications. An additional modification of oxygen, the cyclooctaoxygen, was predicted to exist 1990. The first synthesis characterization cyclooctaoxygen as its sodium crown complex, isolated form three cytosine nucleoside hydrochloride complexes, reported 2016. sperminium hydrogen phosphate/cyclooctaoxygen complex calcula...

Since the Human Genome Project was completed, much attention has been given to genome technologies to regulate target gene expression or function. The most simple and promising approach to down-regulate target gene expression in a living cell is antisense strategy, which prevents translation by hybridization of an oligonucleotide with its complementary RNA strand. For practical use in antisense...

Preparation and magnetic properties of a 3,5-dimethylpyrazolate bridged binuclear copper(II) complex [Qi2(L)(3 ,5-pyz)] (L = l,3-Bis(2-Hydroxy-5-Chlorosalicylideneamino)propan-2-ol) is reported. The crystal structure determined by X-ray diffraction methods. (C22H20N4O3CI2CU2), triclinic, space group PI, a = 9.622(3)hb = 10.921(2), c = 11.420(3) A, q = 100.73(2), ß = 94.04(2), 7 = 108.08(2)°, V ...

To achieve highly-efficient organic light-emitting diodes (OLEDs), great efforts have been devoted into constructing thermally activated delayed fluorescence (TADF) with high horizontal dipole ratios (Θ//). Here, we proposed a design strategy by integrating rigid electron-accepting oxygen-bridged boron core triple electron-donating groups, which exhibited “shamrock-shape”, namely BO-3DMAC and B...

The role of thiophene bridges in determining the photophysical properties of bridged core-modified hexaphyrins is investigated. Depending on the substituted chalcogen atoms and conjugational perturbation across the thiophene bridges, the bridged core-modified hexaphyrins reveal unique photophysical properties.

The E-4,4'-bis[di(p-anisyl)amino]stilbene cation is a class-III mixed-valence species with electronic coupling comparable to that in its biphenyl-bridged analogue, whereas its tolane-bridged analogue belongs to class II.

A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...

The oxidation mechanism of toluene on the surface heat-treated CeO2 nanoparticles was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). When introduced to surface, either chemisorbs an oxygen bound a single cerium atom creating monobound (m) benzyloxy or two neighboring atoms forming bridged (b) benzyloxy. From DRIFTS analysis, benzoate production is direc...
