Cranston, Rosemary R. published the artcileN-type solution-processed tin versus silicon phthalocyanines: Comparison of performance in organic thin-film transistors and in organic photovoltaics, Product Details of C8H4N2, the main research area is tin phthalocyanine silicon organic photovoltaic thin film transistor; photostability solution processing semiconductor.

Tin(IV) phthalocyanines (SnPcs) are promising candidates for low-cost organic electronic devices, and have been employed in organic photovoltaics (OPVs) and organic thin-film transistors (OTFTs). However, they remain relatively understudied compared to their silicon phthalocyanine (SiPc) analogs. Previously, we reported the first solution-processed SnPc semiconductors for OTFTs and OPVs; however, the performances of these derivatives were unexpected. Herein to further study the behavior of these derivatives in OPVs and OTFTs, we report the synthesis along with optical and thermal characterization of seven axially substituted (OR)2-SnPcs, five of which were synthesized for the first time. D. functional theory (DFT) was used to predict charge-carrier mobilities for our materials in their crystal state. The application of these SnPcs as ternary additives in poly(3-hexylthiophene) (P3HT)/phenyl-C61-butyric acid Me ester (PC61BM) OPVs and as semiconductors in solution-processed n-type OTFTs was also investigated. When employed as ternary additives in OPVs, all (OR)2-SnPcs decreased the power conversion efficiency, open-circuit voltage, short-circuit current, and fill factor. However, in OTFTs, four of the seven materials exhibited greater electron field-effect mobility with similar threshold voltages compared to their previously studied SiPc analogs. Among these SnPcs, bis(triisobutylsilyl oxide) SnPc displayed the greatest electron field-effect mobility of 0.014 cm2 V-1 s-1, with a threshold voltage of 31.4 V when incorporated into OTFTs. This difference in elec. performance between OTFT and OPV devices was attributed to the low photostability of SnPcs.

Ishida, Shintaro published the artcileStructures and Properties of Phenylene-Bridged 1,3-Diaza-2-silole and Related 2H-Azasilirenes Obtained by the Reactions of a Dialkylsilylene with Arylnitriles, Safety of Phthalonitrile, the main research area is silylene cycloaddition nitrile dinitrile preparation azasilirene disilolocyclooctene spirocycle; crystal mol structure azasilirene diazasilolocyclooctene spirocycle.

Cycloadditions of diorganosilylenes with nitriles afforded azasilirenes, while phthalonitrile gave dibenzobis[1,3,2]-diazasilolocyclooctene I (10) and spirocycle II (11) with 2,2,5,5-tetra-TMS-1-silacyclopentylidene. Silylene cycloaddition with unsaturated compounds have been extensively explored as convenient and efficient routes to silacycles. Among these, reactions of silylenes with nitriles are still limited and the electronic properties of the resulting azasilacycles such as 2H-azasilirene and 1,3-diaza-2-siloles are less examined We report herein synthesis of a phenylene-bridged 1,3-diaza-2-silole and C-aryl 2H-azasilirenes using cycloaddition reactions of a silylene as well as their structures and UV/Vis absorption spectra. Treatment of an isolable dialkylsilylene, 2,2,5,5-tetra-TMS-1-silacyclopentylidene, with o-phthalonitrile afforded a phenylene-bridged 1,3-diazasilole 10 and an isomeric dearomatized product 11. Similar reactions with p-substituted benzonitriles gave new 2H-azasilirenes. UV/Vis absorption spectra and theor. calculations showed that high-lying n(C:N) orbitals in 1,3-diaza-2-siloles and 2H-azasilirenes and low-lying π*(1,3-diaza-2-silole) orbitals are important for their electronic characters. Computational studies revealed that 1,3-dipolar cycloaddition of silylene nitrile complexes (nitrile silaylides) with the second nitrile and an aromatic C:C bond of 2-cyanophenyl group are key steps for the cycloaddition

Zivkovic, Kristina published the artcileChiral tridentate bis(oxazol-2-ylimino)isoindoline-based pincer ligands: isolation and characterization via deligation from in situ prepared Cd-ligand complexes, Product Details of C8H4N2, the main research area is chiral tridentate oxazolylimino isoindoline pincer cadmium palladium complex preparation; crystal mol structure oxazolylimino isoindoline pincer cadmium palladium complex.

The first isolation and structural characterization of a series of chiral trinitrogen 1,3-bis(4,5-dihydrooxazol-2-ylimino)isoindoline-based pincer ligands are reported. Cadmium complexes, isolated as Cd(L2X)2 where L2X is the deprotonated form of L2XH = 1,3-bis(4,5-dihydro-4-(R)-phenyloxazol-2-ylimino)-isoindoline ((R,R)-5H) or 1,3-bis(4,5-dihydro-4-(S)-iso-propyloxazol-2-ylimino)isoindoline ((S,S)-6H) were prepared in situ via traditional or microwave-based techniques with the latter being more efficient but less able to be scaled up at this time. Ligands (R,R)-5H and (S,S)-6H were isolated via deligation from their resp. cadmium complexes using a thiol-based ligand exchange protocol. The characterization of ligands and their resp. cadmium complexes, in both the solid (x-ray crystallog.) and solution (NMR spectroscopy) states are reported. Pd((S,S)-6)(OAc) is reported as a proof-of-concept of the ability to prepare 1 : 1 ligand to metal ratio complexes that are believed to be necessary as potential enantioselective catalysts.

Zhang, Cheng published the artcileA Design Principle for Polar Assemblies with C3-Sym Bowl-Shaped π-Conjugated Molecules, Safety of Phthalonitrile, the main research area is crystal structure chiral resolution homochiral boron subphthalocyanine complex preparation; C3-sym; bowl-shaped π-conjugated molecule; crystal engineering; polar assembly.

Polar materials attract wide research interest due to their unique properties, such as ferroelectricity and the bulk photovoltaic effect (BPVE), which are not accessible with nonpolar materials. However, in general, rationally designing polar materials is difficult because nonpolar materials are more favorable in terms of dipole-dipole interactions. Here, we report a rational strategy to form polar assemblies with bowl-shaped π-conjugated mols. and a mol. design principle for this strategy. We synthesized and thoroughly characterized 12 single crystals with the help of various theor. calculations Furthermore, we demonstrated that it can be possible to predict whether polar assemblies become more favorable or not by estimating their lattice energies. We believe that this study contributes to the development of organic polar materials and their related studies.

Molaei, Somayeh published the artcileSynthesis of CoFe2O4 @Amino glycol/Gd nanocomposite as a high-efficiency and reusable nanocatalyst for green oxidation of sulfides and synthesis of 5-substituted 1H-tetrazoles, HPLC of Formula: 91-15-6, the main research area is cobalt spinel ferrite magnetite nanoparticles immobilized covalently amino glycol; gadolinium nanocomposite preparation; nickel ferrate magnetite nanoparticles supported on silica immobilized covalently; amino glycol gadolinium nanocomposite preparation; sulfinyl green preparation; tetrazole green preparation.

In this study, a novel gadolinium 2-amino-2-methyl-1,3-propanediol (amino glycol) complex immobilized covalently on CoFe2O4 magnetite nanoparticles was synthesized. The nanocatalyst was characterized thoroughly using thermogravimetric analyzes (TGA), FT-IR spectroscopy, SEM (SEM), energy dispersive X-ray (EDX), inductively coupled plasma optical emission spectroscopy (ICP-OES), vibrational sample magnetometry (VSM), and powder X-ray diffraction (PXRD). CoFe2O4 @amino glycol/Gd was found to be efficient for the oxidation of sulfides to sulfinyl R1S(O)R2 [R1 = Et, Ph, Bn, etc.; R2 = Me, Et, Ph, etc.] and synthesis of 5-substituted 1H-tetrazoles I [R3 = Ph, Bn, 4-HOC6H4, etc.] at mild reaction conditions in the green medium. The influences of reaction temperature, solvent, and the amount of catalysts were studied. The best results were obtained in water and without organic solvent condition for 5-substituted 1H-tetrazoles and oxidation of sulfides, resp. The catalyst was easily collected via an external magnetic field and further reused at least 6 times without a significant decrease in catalytic activity. The wide applicability of the catalyst, ease of catalyst separation, its reusability capacity, and importantly reaction operation in a green medium and elimination of hazardous organic solvents were the advantages of this catalyst.

Grant, Trevor M. published the artcileStraightforward and Relatively Safe Process for the Fluoride Exchange of Trivalent and Tetravalent Group 13 and 14 Phthalocyanines, Quality Control of 91-15-6, the main research area is preparation aluminum gallium trivalent silicon germanium tetravalent phthalocyanine fluoro; cyclic voltammetry aluminum gallium trivalent silicon germanium tetravalent phthalocyanine; thermal decomposition aluminum gallium trivalent silicon germanium tetravalent phthalocyanine.

To avoid the use of hydrofluoric acid, a series of fluorinated trivalent and tetravalent metal containing phthalocyanines (I, II: MPcs) were synthesized using a straightforward one-step halide substitution process using CsF as the fluoride source and in reflux in DMF for less than an hour. The resulting fluoro-MPcs were phys. characterized and compared to the parent chloro-MPcs. In some cases, very little change in properties were observed between the fluoro MPc and the chloro MPc. In other cases, such as F-AlPc, a blue shift in the absorbance characteristics and an increase in oxidation and reduction potential of as much as 0.22 V was observed compared to the chloro derivative Thermo gravimetric anal. (TGA) was performed on all halo-MPcs indicating a change in mass loss profile with heating temperature indicating that the choice of halo substitution on the axial position can have an effect on the decomposition or sublimation temperature of the final compound After initial establishment and characterization of the fluoro-MPcs, the halide substitution reaction of F2-SiPc was further explored by scaling the reaction up to a gram scale as well as considering TBAF as addnl. safe fluoride source. The scaled-up reactions producing F2-SiPc using CsF and TBAF as fluoride exchange sources were successfully reproducible resulting in reaction yields of 100% and 73%, resp. Both processes led to pure final products but CsF, as the fluoride exchange reagent, appears to be the superior reaction process as it has a much higher yield.
