Novel pi-conjugated polymers PSePDBDT1 and PSePDBDT2 containing seleno[3,4-c]pyrrole-4,6-dione and benzo[1,2-b:4,5-b?]dithiophene units were synthesized, and their thermal, optical and photovoltaic properties were compared with those of the corresponding thiophene-based polymer, PTPDBDT2, containing sulfur instead of selenium. PSePDBDT2 exhibited higher thermal stability and a narrower bandgap than PTPDBDT2. Using PSePDBDT2 or PTPDBDT2 as an electron donor and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as an electron acceptor, inverted-type bulk heterojunction photovoltaic devices with the configuration ITO/TiOx/PSePDBDT2 or PTPDBDT2:PC61BM (1:2, w/w)/PEDOT:PSS/Au (ITO = indium tin oxide, TiOx = titanium oxide, PEDOT:PSS = poly(3,4-ethylenedioxythiophene): poly(4-styrene sulfonic acid)) were fabricated. The preliminary power conversion efficiencies of the devices containing PSePDBDT2 and PTPDBDT2 were 0.28% and 1.54%, respectively, under simulated AM1.5 solar irradiation (77.8 mW/cm 2).

The first catalytic formal [5+4] cycloaddition to prepare nine-membered heterocycles is presented. Under palladium catalysis, the reaction of N-tosyl azadienes and substituted vinylethylene carbonates (VECs) proceeds smoothly to produce benzofuran-fused heterocycles in uniformly high efficiency. Highly diastereoselective functionalization of the nine-membered heterocycles through peripheral attack is also demonstrated.

We have developed novel bipolar host materials for high efficiency green phosphorescent OLEDs (PHOLEDs). Phenyl moieties were inserted in a 9,9?-(biphenyl-4,4?-diyl)dicarbazole (CBP) compound to provide much easier electron injection and to increase electron mobility. The efficiency increase and voltage reduction by this modification were observed in green PHOLEDs. At a given constant luminance of 1000 cd/m2, the power efficiency was enhanced about twenty percent in the general green PHOLED devices. Copyright

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), you can also check out more blogs about72287-26-4

In the present study, Fe3O4 nanoparticles were prepared via simple and versatile procedure. Then, a novel and green catalyst was synthesized by the immobilization of Ni on Fe3O4 nanoparticles coated with adenine. The activity of this nanostructure compound was examined for the oxidation of sulfides, oxidative coupling of thiols and synthesis of polyhydroquinolines. The prepared catalyst was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma optical emission spectroscopy (ICP-OES), X-ray Diffraction (XRD), thermal gravimetric analysis (TGA), and vibrating sample magnetometer (VSM) measurements. This organometallic catalyst was recovered by the assistance of an external magnetic field from the reaction mixture and reused for seven continuous cycles without noticeable change in its catalytic activity.

The synthesis of the new potentially tridentate ligand 3,5-bis(dimethylaminomethyl)pyridine (3) is described. Coordination chemistry of this ligand has been investigated with PdII and PtII precursor compounds. Both a bidentate bridging bonding motif and a monodentate bonding mode is observed. The latter compounds incorporate 3 by coordination through the pyridinic N atom only. The former complexes contain ligand 3 bonded to 2 metal centres by bridging through coordination of one trialkyl N donor atom and the pyridinic N atom. The solid-state structure of a ligand bridged Pd dimer has been elucidated by single-crystal X-ray diffraction and corroborates with the solid-state IR data that suggested a trans-PdCl2 unit was present.

An efficient route to 4-substituted quinazolines by arylation or alkylation of quinazolinones under mild conditions is described. 4-Tosyloxyquinazolines were obtained through the reaction of quinazolinones and p-methylbenzenesulfonyl chloride in the presence of K2CO3. The cross-coupling reaction of 4-tosyloxyquinazolines with organoindium reagents, carried out in tetrahydrofuran, catalyzed by Pd2(dba)3/ (2-furyl)3P led to the formation of 4-functionalized quinazolines in good to excellent yields. Higher yields were obtained by the one-pot reaction of quinazolinone, p-methylbenzenesulfonyl chloride, Pd2(dba)3-/(2-furyl)3P, and organoindium reagent. These methods using organoindium compounds as coupling partners provided an efficient route to 4-(hetero)aryl/alkylquinazolines, especially 4-substituted quinazolines bearing a halogen scaffold.

A concise and diversity-oriented route to trifluoromethylbenzo[b]furans has been devised. A variety of phenols are directly converted to the corresponding 2-methylthio-3-trifluoromethylbenzo[b]furans by new triflic-anhydride-mediated extended Pummerer annulation reactions with trifluoromethylketene dithioacetal monoxide. The methylthio group of the products undergoes further transformations, which increase the diversity of available trifluoromethylbenzo[b]furans.

We report a Suzuki-Miyaura cross-coupling reaction of 1,8-diaminonaphthalene (dan)-protected arylboronic acids in the presence of KOt-Bu, which does not require the removal of the dan moiety. Notably, the use of aryl-B(dan) in the Suzuki-Miyaura reaction provides a complementary solution to the protodeboronation problems. The base KOt-Bu plays a crucial role for the promotion of these cross-coupling reactions as it enables the formation of a borate salt. This reaction protocol was extended to the one-pot sequential Suzuki-Miyaura cross-coupling reaction of 4-[(pin)B]C6H4-B(dan), wherein the “less reactive” aryl-B(dan) moiety was cross-coupled preferentially.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 52522-40-4
