A novel dinuclear platinum complex of (dfppy-mhb-dfppy)Pt(2)(acac)(2) was synthesized and characterized, where dfppy-mhb-dfppy is a binary C^N cyclometalated ligand containing two bridged 2,4-difluorophenylpyridine (dfppy) units and acac is 2,4-pentanedione anion. Compared to previously reported dinuclear platinum complexes with a binary ancillary ligand, this dinuclear platinum complex showed ...

By comparing the phosphorescence spectra of Gd(acac)3 (acac~acetylacetone), Gd(TFacac)3 (TFacac~ 1,1,1-trifluoroacetylacetone), the effects of fluorine replacement of hydrogen on the triplet state energy of the ligands were revealed. Fluorine can lower the triplet state energy of Hacac and make it more suitable for energy transfer towards the D4 state of terbium. Organic electroluminescent devi...

A pair of chemical isomeric structures of novel N-tert-butylphenyl thenoylhydrazide compounds I and II were designed and synthesized. Their structures were characterized by MS, IR, (1)H NMR, elemental analysis and X-ray single crystal diffraction. The regioselectivity of the Meerwein arylation reaction and the electrophilic substitution reaction of N-tert-butyl hydrazine were studied by density...

The rates of C H bond activation for various alkanes by [(N-N)Pt(Me)(TFEd(3))](+) (N N = Ar N C(Me) C(Me) N Ar; Ar = 3,5-di-tert-butylphenyl; TFE-d(3) = CF(3)CD(2)OD) were studied. Both linear and cyclic alkanes give the corresponding alkene-hydride cation [(N-N)Pt(H)(alkene)](+) via (i) rate determining alkane coordination to form a C H sigma complex, (ii) oxidative cleavage of the coordinated...

We demonstrated a novel microfluidic white organic light-emitting diode (microfluidic WOLED) based on integrated sub-100-μm-wide microchannels. Single-μm-thick SU-8-based microchannels, which were sandwiched between indium tin oxide (ITO) anode and cathode pairs, were fabricated by photolithography and heterogeneous bonding technologies. 1-Pyrenebutyric acid 2-ethylhexyl ester (PLQ) was used as...

This communication reports the spectroscopic characterizations of mixed Langmuir–Blodgett (LB) films of non-amphiphilic N,N-bis (2,5-di-tert-butylphenyl)3,4,9-perylenedicarboximide (DBPI) molecules, mixed with polymethyl methacrylate (PMMA) and stearic acid (SA). Jaggregates of DBPI molecules in the mixed LB films have been confirmed by UV–Vis absorption spectroscopic study. Formation of organi...

Chemicals. All chemicals were reagent grade and almost all were obtained from British Drug Houses Ltd, Poole, Dorset. The exceptions were : butyl-PBD [2-(4-tert-butylphenyl)5-(4-biphenylyl)-1, 3,4-oxadiazole] from Koch Light Laboratories Ltd, Colnbrook, Buckinghamshire; malt extract (L 39) and agar no. 3 (L 13) from Oxoid Ltd, London; L-[U-WC]aspartate (227 mCi/mmol), L-[ U-14C]glutamate (I 4.7...

The anti-Trypanosoma cruzi activity of 5-nitro-2-furfuriliden derivatives as well as the cytotoxicity of these compounds on J774 macrophages cell line and FN1 human fibroblast cells were investigated in this study. The most active compounds of series I and II were 4-butyl-[N'-(5-nitrofuran-2-yl) methylene] benzidrazide (3g; IC50=1.05μM±0.07) and 3-acetyl-5-(4-butylphenyl)-2-(5-nitrofuran-2-yl)-...

One promising method to pattern full color polymer Organic Light-Emitting Diode (OLED) displays is to print dye from a pre-patterned organic film onto a spin-cast polymer and then diffuse the dye into the film at room temperature in a solvent vapor environment. This method utilizes the well-known tendency for a polymer film to absorb solvent vapor, which depresses the glass transition temperatu...

Novel compounds with significant medicinal properties have gained much interest in therapeutic approaches for treating various inflammatory disorders like arthritis, odema and snake bites and the post-envenom (impregnating with venom) consequences. Inflammation is caused by the increased concentration of secretory Phospholipases A(2) (sPLA(2)s) at the site of envenom. A novel compound Tris(2,4-...
