Phosphorus-based heteropentacenes: Efficiently tunable materials for organic n-type semiconductors

Benzo-condensed dithieno[3,2-b:2′,3′-d]phospholes have been synthesized that allow convenient tuning of properties that are essential for application as semiconductor materials in organic field-effect transistor (OFET) devices. The versatile reactivity of the trivalent phosphorus atom in these heteropentacenes provides access to a series of materials that show different photophysical properties, significantly different organization in the solid state, and distinctly different electrochemical properties that can be achieved by simple chemical modifications. The materials show strong photoluminescence in solution and in the solid state that depends on the electronic nature of the phosphorus center. Electrochemical studies revealed that the phosphorus atom intrinsically furnishes materials with n-channel or ambipolar behavior, also depending on its electronic nature. The experimental data were verified by DFT quantum chemical calculations and suggest that the phosphorus-based heteropentacenes could be excellent candidates for n-channel OFET semiconductor materials.

Aminobenzoannulated hetero- and carbocycles from 2-azahepta-2,4-dien-6- ynyllithium compounds: Scope and limitation of a novel benzoannulation reaction

Deprotonation of the N-benzylhetarylmethanimines 9, 12, 15, and 18 at -78C with subsequent warming to room temperature over 16 hours and treatment with electrophiles furnished polysubstituted aminobenzoannulated heterocycles 19-25 in good to excellent yields. In a similar fashion, the deprotonation of the N-allyl-2-(alk-1-ynyl)phenylmethanimines 26 and 27 led to 2-vinylnaphthalen-1-amines 28 and 29, respectively, in moderate yields. The reaction of N-[(trimethylsilyl)methyl]imine 31 afforded naphthalen-1-amine 33, unsubstituted at the ortho position after removal of the trimethylsilyl group. The deprotonation of imine 34, bearing a trimethylsilyl group on the C?C bond, gave none of expected amines, but the substituted imine 35, whose structure was identified using 2D NMR spectroscopy.

Anti-HIV-1 activity of resveratrol derivatives and synergistic inhibition of HIV-1 by the combination of resveratrol and decitabine

Ribonucleotide reductase inhibitors enhance the anti-HIV-1 activities of a variety of nucleoside analogs, including those that act as chain terminators and those that increase the HIV-1 mutation rate. However the use of these ribonucleotide reductase inhibitors is limited by their associated toxicities. The hydroxylated phytostilbene resveratrol has activity in a host of systems including inhibition of ribonucleotide reductase and has minimal toxicity. Here we synthesized derivatives of resveratrol and examined them for anti-HIV-1 activity and their ability to enhance the antiviral activity of decitabine, a nucleoside analog that decreases viral replication by increasing the HIV-1 mutation rate. The data demonstrates that six of the derivatives have anti-HIV-1 activity greater than resveratrol. However, only resveratrol acted in synergy with decitabine to inhibit HIV-1 infectivity. These results reveal novel resveratrol derivatives with anti-HIV-1 activity that may have mechanisms of action that differ from the drugs currently used to treat HIV-1.

Synthesis and properties of ladder-type 1,4-dihydro-1,4-phosphasilins

The synthesis and advanced characterization of a series of extended dithieno[2,3-b:3′,2′-e][1,4-dihydro-1,4]phosphasilins is reported, and their suitability as new building blocks for organic electronics is evaluated. Synthesis of basic, as well as benzo-extended dithienophosphasilins, can be achieved using appropriate 2,3-dibromothiophene precursors in a two-step protocol introducing the silicon and phosphorus centers subsequently. Both ladder-type materials show the typical reactivity of trivalent phosphorus species and can quantitatively be converted into the corresponding oxides or gold complexes, the latter exemplified with the basic dithienophosphasilin. Their optoelectronic properties were found to be inferior to those of related dithieno[3,2-b:2′,3′-d]phospholes, indicating a disruption of the pi-conjugation in the molecular scaffold. X-ray crystallographic studies revealed that the molecular scaffold is planar in the oxidized benzo-extended material, whereas the basic dithieno materials show some small deviation from planarity. Density functional theory calculations suggest all materials to be planar, with the exception of the benzo-extended trivalent phosphasilin. This structure-property study illustrates that the disruption of the pi-conjugation in the molecular scaffold of the extended phosphasilins is exclusively due to the presence of the silicon center and its electronic effects, rather than structural features.

Sodium halides as the source of electrophilic halogens in green synthesis of 3-halo- and 3,n-dihalobenzo[b]thiophenes

A convenient methodology for the synthesis of mono- and di-halogenated benzo[b]thiophenes is described herein, which utilizes copper(II) sulfate pentahydrate and various sodium halides in the presence of substituted 2-alkynylthioanisoles. The proposed method is facile, uses ethanol as a green solvent, and results in uniquely substituted benzo[b]thiophene structures with isolated yields up to 96%. The most useful component of this methodology is the selective introduction of bromine atoms at every available position (2?7) around the benzo[b]thiophene ring, while keeping position 3 occupied by a specific halogen atom such as Cl, Br or I. Aromatic halogens are useful reactive handles; therefore, the selective introduction of halogens at specific positions would be valuable in the targeted synthesis of bioactive molecules and complex organic materials via metal-catalyzed cross coupling reactions. This work is a novel approach towards the synthesis of dihalo substituted benzo[b]thiophene core structures, which provides a superior alternative to the current methods discussed herein.

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.Recommanded Product: 2,3-Dibromobenzo[b]thiophene, you can also check out more blogs about6287-82-7
