Beyond traditional light-emitting electrochemical cells-a review of new device designs and emitters

In the field of solid-state lighting (SSL) technologies, light-emitting electrochemical cells (LECs) are the leading example of easy-to-fabricate and simple-architecture devices. The key-aspect of this technology is the use of a single active layer that consists of a mixture of an emitter and an ionic polyelectrolyte. The presence of mobile anions efficiently assists both charge injection and charge transport processes using air-stable electrodes. This concept reported in the mid-90s was considered as a game-changer approach, leading to a new field in SSL. Since then, the evolution of the LEC technology has involved different stages, namely (i) the search for the best combination of emitters (luminescent conjugated polymers and ionic transition complexes) and additives (ionic polyelectrolytes, ionic liquids, and neutral polymers), (ii) the understanding of the device mechanism using several techniques like electrostatic force microscopy (EFM), microcavity effects, scanning Kelvin probe microscopy (SKPM), time-of-flight secondary ion mass spectroscopy (ToF-SIMS), electrochemical impedance spectroscopy (EIS), etc., (iii) the development of simple and up-scalable device fabrication processes and, recently, (iv) the quest for new emitters like copper(i) complexes, small-molecules, quantum dots, and perovskites. This review provides a general overview of the first three points and, in particular, an in-depth revision of the recent advances in designing new architectures and emitters for LECs.

Hybridization dependent cleavage of internally modified disulfide-peptide nucleic acids

Selectivity of the cleavage of single stranded over hybridized forms of internally modified disulfide-peptide nucleic acids (PNA) has been optimized using a series of phosphines and thiols, which have different sizes and charges. For the most selective cleaver found (tris-(carboxyethyl)-phosphine), reactivity of single stranded PNA is 33 times higher than that of the PNA-DNA duplex. Selectivity of single stranded disulfide-PNA cleavage has been explained in terms of electrostatic interaction between the substrate and the cleaver.

alpha, beta-Alkynone Accelerated PPM Level Pd-Catalyzed Sonogashira Coupling Reaction

In the palladium-catalyzed C?C coupling reaction, electron-rich phosphine ligands and a catalytic amount of catalyst loading are required in most cases. Herein, a bench-stable, easily modified and less toxic alkynone was utilized in palladium-catalyzed Sonogashira coupling to replace conventional phosphine ligands. With 1-(4-methoxyphenyl)-3-phenyl-2-yn-1-one (L2) as the ligand, catalyst loading was reduced to 5-10 ppm. In this newly developed catalytic system, a variety of (hetero)arene iodines and alkynes could be tolerated, resulting in good yields of the corresponding cross-coupling products.

Novel electron-rich bulky phosphine ligands facilitate the palladium-catalyzed preparation of diaryl ethers

A general method for the palladium-catalyzed formation of diaryl ethers is described. Electron-rich, bulky aryldialkylphosphine ligands, in which the two alkyl groups are either tert-butyl or 1-adamantyl, are the key to the success of the transformation. A wide range of electron-deficient, electronically neutral and electron-rich aryl bromides, chlorides, and triflates can be combined with a variety of phenols with the use of sodium hydride or potassium phosphate as base in toluene at 100 C. The bulky yet basic nature of the phosphine ligand is thought to be responsible for increasing the rate of reductive elimination of the diaryl ether from palladium.

Decarbonylative Borylation of Amides by Palladium Catalysis

The development of transition-metal-catalyzed borylation reactions is of significant importance for the fields of organic synthesis and medicinal chemistry because of the versatility of organoboron functional groups. Herein, we report the direct decarbonylative borylation of amides by highly selective carbon-nitrogen bond cleavage by palladium catalysis. The approach capitalizes on the ground-state destabilization of the amide bond in N-acyl glutarimides to achieve Pd-catalyzed insertion into the amide N-C bond and decarbonylation (deamidation). Mechanistic studies and the utility of this methodology in orthogonal sequential cross-couplings of robust, bench-stable amides are reported.

PdCl[PPh2CH2CH2CH-(cyclic)CH2CH2PPh2] as a precursor to homo- and hetero-metallic species directed by ESMS (electrospray ionisation mass spectrometry)

The cyclometallated Pd compound PdCl[PPh2CH2CH2CH-(cyclic)CH2CH2PPh2]1, obtained from PdCl2(Ph2P(CH2)5PPh2) in refluxing DMF (N,N-dimethylformamide), was characterized by NMR and X-ray single-crystal diffraction analysis. The cyclometallation of MCl2(Ph2P(CH2)5PPh2) (M = Pd, Pt) to give 1 and its Pt(II) analogue was probed using electrospray ionisation mass spectrometry (ESMS). The reactivity of 1 towards neutral ligands such asphosphines and pyridines as well as basic metal complexes such as pyrid ine-thiolate compounds of Au(I), Hg(II) and Pt(II) in solution was also investigated. The results showed that the chloride trans to the Pd-C bond is susceptible to ligand replacement. A number of entry metalloligandswas examined in an attempt to establish a route to cyclometallated aggr egates and clusters.

ESR study of paramagnetic derivatives of sterically hindered di-o-quinone with the tetrathiafulvalene bridge

The paramagnetic derivatives of 4,4?,7,7?-tetra-tert-butyl-2, 2?-bis-1,3-benzodithiol-5,5?,6,6?-tetraone (1), viz., radical anion salts of the alkali metals (Li, Na, K) and cobaltocenium cations, chelated mono-o-semiquinone complexes with different metal fragments (Tl, TlMe 2, SnPh3, Mn(CO)4, Mn(PPh3)(CO) 3), a number of copper(I) complexes with sterically hindered phosphines as well as binuclear heterometallic derivatives of triphenylantimony(V) o-semiquinone-catecholate with the analogous paramagnetic centers, were studied by ESR spectroscopy. The reaction of di-o-quinone 1 with sodium amalgam resulted in the formation of all reduced forms including quinone-semiquinone, disemiquinone, semiquinone-catecholate, and dicatecholate. A radical cation with the unpaired electron localized on the tetrathiafulvalene (TTF) fragment, which resulted from the oxidation of di-o-quinone 1, was detected by ESR spectroscopy.
