Recyclable Cu(II)-Coordination Crosslinked Poly(benzimidazolyl pyridine)s as High-Performance Polymers

Crosslinked high-performance polymers have many industrial applications, but are difficult to recycle or rework. A novel class of recyclable crosslinking Cu(II)-metallo-supramolecular coordination polymers are successfully prepared, which possess outstanding thermal stability and mechanical property. More importantly, the Cu2+ coordination interactions can be further removed via external pyrophosphate to recover the linear polymers, which endow the crosslinking polymers with recyclability.

Catalytic enantioconvergent decarboxylative allylic alkylation of allyl indolenin-3-carboxylates

A catalytic enantioconvergent process has been developed for the conversion of racemic allyl indolenin-3-carboxylates into enantiomerically enriched C3-quaternary indolenines. A Pd-catalyzed decarboxylative allylic alkylation reaction was employed for both stereoablation of the racemic allyl indolenin-3-carboxylates and enantioselective formation of the quaternary carbon center. The enantioconvergent conversion of racemic allyl indolenin-3- carboxylates into enantiomerically enriched C3-quaternary indolenines is reported.

An efficient class of bis-NHC salts: Applications in Pd-catalyzed reactions under mild reaction conditions

This study describes an efficient class of bis-N-heterocyclic carbene (bis-NHC) salts that can be easily made from commercially available and inexpensive starting materials. The application of these salts to Pd-catalyzed reactions is described. The palladium (Pd) catalyst generated in situ was highly effective under mild reaction conditions.

Metal-Dependent DNA Recognition and Cell Internalization of Designed, Basic Peptides

A fragment of the DNA basic region (br) of the GCN4 bZIP transcription factor has been modified to include two His residues at designed i and i+4 positions of its N-terminus. The resulting monomeric peptide (brHis2) does not bind to its consensus target DNA site (5?-GTCAT-3?). However, addition of Pd(en)Cl2 (en, ethylenediamine) promotes a high-affinity interaction with exquisite selectivity for this sequence. The peptide-DNA complex is disassembled by addition of a slight excess of a palladium chelator, and the interaction can be reversibly switched multiple times by playing with controlled amounts of either the metal complex or the chelator. Importantly, while the peptide brHis2 fails to translocate across cell membranes on its own, addition of the palladium reagent induces an efficient cell internalization of this peptide. In short, we report (1) a designed, short peptide that displays highly selective, major groove DNA binding, (2) a reversible, metal-dependent DNA interaction, and (3) a metal-promoted cell internalization of this basic peptide.

Synthesis and solid state and solution characterization of mono- and di-(eta1-C) carbamoyl-palladium complexes. New efficient palladium-catalyzed routes to carbamoyl chlorides: Key intermediates to isocyanates, carbamic esters, and ureas

The catalytic conversion of primary and secondary amines into isocyanates or carbamoyl chlorides is performed using palladium complexes. The palladium-based catalytic systems is very active and avoids the synthesis of phosgene. The palladium (II) complex reacts with amine and CO to produce the carbamoyl complexes. The carbamoyl complexes are reacted with halogen donors with the elimination of the carbamoyl ligands as isocyanates or carbamoyl chlorides.

Synthesis, optoelectronic properties and photovoltaic performances of wide band-gap copolymers based on dibenzosilole and quinoxaline units, rivals to P3HT

Three pi-conjugated alternating copolymers, based on dibenzosilole as an electron-rich unit and fluorinated or non-fluorinated quinoxaline as an electron-withdrawing unit, connected through thiazole or thiophene moieties, have been synthesized, fully characterized and applied as donors in polymer solar cells (PSCs). The three copolymers, namely PDBS-TQx, PDBS-TQxF and PDBS-TzQx, belong to the wide band-gap semiconductor materials family, and they show an absorption edge in the visible region close to 650 nm. In order to tune the position of the polymer energy levels, and in particular to decrease their HOMO energy level, we compare the use of a thiazole spacer sandwiching the electron-deficient moiety as an alternative way to the popular backbone fluorination. PSCs based on a blend of PDBS-TQx and [6,6]-phenyl-C71-butyric acid methylester (PC71BM) as an active layer have shown the best device performances with a maximum power conversion efficiency (PCE) of 5.14% for the active area of 0.28 cm2 (under standard illumination of AM 1.5G, 1000 W m-2). Interestingly this polymer outperforms P3HT:(PC61BM) solar cells used as a reference material in this work. In addition to the thorough characterization data, including among other spectroscopy techniques, XRD, OFET, AFM and nc-AFM, we discuss in detail the relationship between the chemical structures of the three polymers, their optoelectronic properties, the phase separation in blends with PC71BM and their photovoltaic performances.
