Ethanol-Processable, Highly Crystalline Conjugated Polymers for Eco-Friendly Fabrication of Organic Transistors and Solar Cells

We report eco- and human-friendly fabrication of organic field-effect transistors (OFETs) and polymer solar cells (PSCs) using only ethanol as a processing solvent at ambient condition, in stark contrast to that involving the use of halogenated and/or aromatic solvents. New ethanol-processable electroactive materials, p-type polymer (PPDT2FBT-A) and n-type bis-adduct fullerene acceptor (Bis-C60-A) are designed rationally by incorporation of oligoethylene glycol (OEG) side-chains. By ethanol processing, PPDT2FBT-A shows a broad light absorption in the range of 300-700 nm and highly crystalline interchain ordering with out-of-plane interlamellar scattering up to (400) with strong pi-pi stacking. As a result, the ethanol-processed PPDT2FBT-A OFETs yield high charge-carrier mobilities up to 1.0 × 10-2 cm2 V-1 s-1, which is the highest value reported to date from alcohol-processed devices. Importantly, the ethanol-processed PPDT2FBT-A OFET outperformed that processed using typical processing solvent, chlorobenzene (CB), with ?10-fold enhancement in hole mobility, because the highly edge-on oriented packing of PPDT2FBT-A was produced by ethanol-process. Also, for the first time, significant photovoltaic performance was achieved for the ethanol-processed device of PPDT2FBT-A and Bis-C60-A due to the formation of an interpenetrating nanofibrillar morphology of highly crystalline PPDT2FBT-A polymers. The relationships between molecular structure, nanoscale morphology and electronic properties within ethanol-processed OFETs and PSCs were elucidated by comparing to typical CB-processed devices. These comparisons provide important guidelines for the design of new ethanol/water-soluble active layer materials and their use in the development of green solvent-processed efficient OFETs and PSCs.

Total synthesis of an atropdiastereomer of RP-66453 and determination of its absolute configuration

The absolute configuration (aR, S, S, S, S, S) was assigned to the natural product RP-66453 (1) after the total synthesis of its atropdiastereomer and spectroscopic studies on the two compounds. A sequence of SNAr-based cyclo-etherification and an intramolecular atropdiastereoselective Suzuki-Miyaura coupling were used for the construction of the elusive A-B-O-C bicyclic skeleton of RP-66453.

Palladium-catalyzed N1-selective allylation of indoles with allylic alcohols promoted by titanium tetraisopropoxide

The direct N1-selective allylation of indoles with allylic alcohols has been accomplished by synergistic functions of palladium catalysts and titanium tetraisopropoxide. The site selectivity is notably different from that observed in other related transition metal-catalyzed approaches. This chemistry provides a facile route to a variety of allylated indoles in synthetically useful yields. The utility of this simple allylation reaction was demonstrated with the first total synthesis of (+)-N-(4?-hydroxyprenyl)-cyclo(alanyltryptophyl), which was completed in five steps, starting from l-tryptophan methyl ester hydrochloride.

Pd/pivalic acid mediated direct arylation of 2-pyrones and related heterocycles

Abstract Direct arylation represents a favourable alternative to traditional cross-coupling reactions and has found widespread use with simple aryls and robust heterocycles. Herein a direct arylation protocol has been optimised and applied to more delicate, privileged biological motifs. The intramolecular direct arylation of 2-pyrones, 2-coumarins, 2-pyridones and 2-quinolones occurs in very good to excellent yields using a Pd0 source and pivalic acid as a crucial additive. Preliminary mechanistic investigations were also carried out. Direct Arylation represents a favourable alternative to traditional cross-coupling reactions. However there are limited reports on application to more delicate, privileged biological motifs. Herein the intramolecular Pd/PivOH promoted direct arylation of 2-pyrones, 2-coumarins, 2-pyridones and 2-quinolones is reported. One intermolecular example is included along with preliminary mechanistic investigations.

A practical, ligand-free, palladium-catalyzed isocyanide insertion reaction for the construction of novel ring-fused quinazolinones

A high-yielding, ligand-free, palladium-catalyzed isocyanide insertion reaction for the synthesis of phthalazino[1,2-b]quinazolinones from the readily obtainable quinazolinones has been developed. Easily handled and relatively low-cost palladium(II) acetate was used as the catalyst, without an additional ligand. Preparation of the quinazolinones involved the cascade reaction of isatoic anhydrides, phenylhydrazines and 2-bromobenzaldehyde catalyzed by p-toluenesulfonic acid in one pot. This novel protocol may be applicable for the synthesis of other important ring-fused heterocyclic compounds. Georg Thieme Verlag Stuttgart. New York.

Well-defined bisMETAMORPhos PdI-PdI complex: Synthesis, structural characterization, and reactivity

The formation of a bisMETAMORPhos PN-bridged dimeric PdI complex (3) from ligand 1 and Pd(dba)2 is described. The addition of 1 to Pd(dba)2 initially leads to the formation of Pd0 complex 2, which has a highly distorted tetrahedral environment and binds two neutral ligands 1. Complex 2 converts to {PdI}2 complex 3 upon heating. Complex 3 consists of a completely flat Pd-Pd core, with a Pd-Pd bond length of 2.6199(4) A, and the Pd centers display a highly distorted square planar coordination environment. The formation of complex 3 from 2 is suggested to proceed via an in situ comproportionation pathway. Initial decoordination of one ligand from 2 followed by oxidative addition of one neutral coordinated ligand arm leads to a 1-PdIIH complex. Insertion of free dba into the Pd-H bond generates a 1-PdIIdba complex that releases 1,5-diphenylpent-1-en-3-one via intra- or intermolecular protonolysis. Concomitantly, comproportionation with 1-Pd0 yields 3. Complex 3 was found to function as a precatalyst in the Suzuki-Miyaura cross-coupling of p-chloroacetophenone with good conversions.

(E)- and (Z)-beta-borylallylsilanes by alkyne silaboration followed by regio- and stereoselective double-bond migration

Double take: beta-Borylallylsilanes have been synthesized by the regioselective silaboration of terminal alkynes followed by palladium-catalyzed double-bond migration of the resulting beta-borylalkenylsilanes (see scheme). The stereoselectivity of the double-bond migration can be controlled by additives, thus leading to the stereocomplementary synthesis of (E)- and (Z)-beta-borylallylsilanes. Copyright

Spectral and photophysical properties of mono and dinuclear Pt(II) and Pd(II) complexes: An unusual emission behaviour

Mononuclear complexes of the formula [M(N-N)(DHB)] and dinuclear complexes of the formula [M2(BPY)2(THB)] were synthesized and characterized. These complexes were found to show an optically active LLCT band and the platinum complexes of the series were found to show dual emitting states. Eight mononuclear complexes of the formula [M(N-N)(DHB)] and two binuclear complexes of the formula [M2(BPY)2(THB)] {where M = Pd(II) or Pt(II), N-N = 2,2?-bipyridine (BPY), 2,2?-biquinoline (BIQ), 4,7-diphenyl-1,10-phenanthroline (DPP), 1,10-phenanthroline (PHEN); DHB = dianion of 3,4-dihydroxybenzaldehyde and THB = tetraanion of 3,3?,4,4?-tetrahydroxy benzaldazine} were prepared and their electrochemical, spectral and photophysical properties were examined. These complexes were characterized by chemical analysis, IR and proton NMR spectroscopy. A detailed study on the absorption spectroscopy of these complexes was made. These complexes were found to show a low-energy solvatochromic ligand-to-ligand charge-transfer (LLCT) band. The electronic energies of these bands have been analyzed and compared with electrochemical data. Emission behaviour of the complexes of the series, [Pt(N-N)(DHB)], [Pt(N-N)(DHBA)] {where DHBA is the dianion of 3,4-dihydroxybenzoic acid} and [Pt2(BPY) 2(THB)] was also investigated. These platinum complexes were found to emit from a low-energy state at low temperature and a high-energy state at room temperature. Photophysics of these complexes is also discussed.
