A new alternating polymer (PBDTFQx) with alkoxy-substituted benzo[1,2-b:4,5-b?]dithiophene (BDT) as donor and fluorine-functionalized quinoxaline derivative (FQx) as acceptor, was synthesized and characterized using NMR, UV-vis spectroscopy, thermogravimetric analyses (TGA), and cyclic voltammetry. Photovoltaic devices with the configuration of ITO/poly(3,4- ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT:PSS)/PBDTFQx: [6,6]-phenyl C61-butyric acid methyl ester (PC61BM)/LiF/Al were fabricated, in which PBDTFQx performed as the electron donor and PC 61BM as the electron acceptor. When the optimized weight ratio of PBDTFQx:PC61BM reached 1:2, the photovoltaic device exhibited acceptable performance with the open-circuit voltage (Voc), the short-circuit current density (Jsc), the fill factor (FF), and the power conversion efficiency (PCE) of 0.77 V, 2.46 mA/cm2, 0.54% and 1.02%, respectively. The experimental data implied that PBDTFQx would be a promising donor candidate in the application of polymer solar cells.

A method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu2Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biologically active compounds via the boronate esters. The unique capabilities of this method are demonstrated by combining carbon-boron bond-forming reactions with palladium-catalyzed methylation in a tandem transformation.

Unlocking the dynamics of the evolution of the excited state at the complicated titania/dye/electrolyte interface in organic dye-sensitized solar cells is crucial to provide a basis for the rational design of low-energy-gap organic photosensitizers. By constructing two organic donor-acceptor dyes composed of benzothiadiazole-benzoic acid (BTBA) and pyridothiadiazole-benzoic acid (PTBA) as electron acceptors, we have identified the images of multiple-step relaxations of the excited state and multiple-state electron injections at the titania/dye/electrolyte interface using ultrafast transient absorption spectroscopic measurements in conjunction with theoretical simulations. Density functional theory and time-dependent density functional theory calculations indicate that there should be torsion-induced excited state relaxations from an optically generated ?hot? excited state to the equilibrium excited state characteristic of a more planar conjugated backbone and a quinonoid structure for dye molecules on the titania surface, suggesting the probable presence of multiple-state electron injections at the titania/dye/electrolyte interface. In virtue of a target analysis of femtosecond transient absorption spectra, we have found that the dye with PTBA features a much lower overall electron injection yield with respect to the dye with BTBA owing to the sluggish electron injection and short lifetime of the excited state, accounting for a lower maximum of external quantum efficiencies of the device made from the dye with PTBA as an acceptor.

The rapid generation of molecular complexity from simple reactants is a key challenge in organic synthesis. Spiro compounds, underrepresented 3D motifs in chemical libraries, represent a challenge due to the creation of spiro quaternary carbon and the need to control the 3D shape in one step. Herein, we report the first ring contraction/formal [6 + 2] cycloaddition using synergistic Pd(0)/secondary amine catalysis, obtaining [5,5]-spiropyrazolone derivatives in excellent yields and stereoselectivities. We demonstrate that this reaction has a broad scope of early and late stage derivatization that will benefit the creation of highly valuable chemical libraries using spiropyrazolone motifs. We detected the key palladium activated intermediate in its protonated form by mass spectrometry and characterized its structure by infrared spectroscopy and DFT calculations, allowing us to propose a conceivable mechanistic pathway for this reaction.

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.Quality Control of Pd2(DBA)3, you can also check out more blogs about52409-22-0

Synthesis of 1-substituted 1-siloxy-3-aryloxybuta-1,3-dienes is achieved starting with readily available methyl ketones by a reaction sequence involving a palladium-catalyzed addition of the ketone to a 3,5-xylyl triisopropylsilylethynyl ether followed by isomerizations. This synthetic method is applicable to various methyl ketones. Cycloaddition of the resulting dienes with electron-deficient alkenes and alkynes gives 6-membered carbo- and heterocycles.

Solid-state packing and polymer orientation are critical for achieving high charge carrier mobility in organic thin-film transistors. Four side chain substituents, 2-octyldodecyl (?20), 4-octyltetradecyl (?22), 2-decyltetradecyl (?24), and 4-decylhexadecyl (?26), were synthesized to study the effect of side chains on the molecular crystallinity and charge transport properties of diketopyrrolopyrrole?thieno[3,2-b]thiophene copolymers (DPPTTs). Achieving high-performance DPP-based polymers not only depends on crystallinity, but also on the appropriate proportions of polymer chain orientations. DPPTT22 and DPPTT26 have more coplanarity of the backbone structure and a shorter pi?pi stacking distance, but the charge mobilities are limited. The objective of this study is to determine the influence of different side chains on the layer distance and pi?pi stacking regarding 3D carrier channel formation. However, a favorable morphology is also important to improve the charge mobility. DPPTT24 shows improved mobility due to its suitable edge-on-oriented crystallinity and well-interconnected domains with small grain boundaries.
