22-10-2014 | Hayato Tsuji; Chikahiko Mitsui; Eiichi Nakamura, Chemical Communication, 2014
The hydrogen/deuterium primary kinetic isotope effect provides useful information about the degradation mechanism of OLED host materials. Thus, replacement of labile C–H bonds in the host with C–D bonds increases the device lifetime by a factor of five without loss of efficiency, and replacement ...
21-10-2014 | Yasuhiro Shiraishi; Yusuke Kofuji; Shunsuke Kanazawa; Hirokatsu Sakamoto; Satoshi Ichikawa; Shunsuke Tanaka; Takayuk ..., Chemical Communication, 2014
Platinum (Pt) nanoparticles with <4 nm diameter loaded on graphitic carbon nitride (g-C3N4) by reduction at 673 K behave as efficient co-catalysts for photocatalytic hydrogen evolution under visible light (λ
21-10-2014 | Solène Savourey; Guillaume Lefèvre; Jean-Claude Berthet; Thibault Cantat, Chemical Communication, 2014
A novel methodology is presented for the direct methylation of amines, using formic acid as a unique source of carbon and hydrogen. Based on ruthenium(ii) catalysts, the formation of the N–CH3 group proceeds via an efficient formylation/transfer hydrogenation pathway.
21-10-2014 | L. Čechová; E. Procházková; I. Císařová; M. Dračínský; Z. Janeba, Chemical Communication, 2014
While purifying new polysubstituted 5-nitrosopyrimidines, the unique separation of pairs of rotamers as chemical species, stabilized by a single intramolecular hydrogen bond and differing only in nitroso group orientation, was achieved. This interesting stereochemical phenomenon is compared to ...
21-10-2014 | Cameron M. Moore; Nathaniel K. Szymczak, Chemical Communication, 2014
Chemical reduction of a tripodal Cu(ii)–F complex containing pendent hydroxyl groups results in the partial dissociation of a F− ligand from Cu. The resulting Cu(i) complex is characterized as containing an outer sphere F− anion ‘captured’ by hydrogen bonds. The pendent hydroxyl groups were found ...
15-10-2014 | Keishiro Tahara; Tetsufumi Nakakita; Shohei Katao; Jun-ichi Kikuchi, Chemical Communication, 2014
Triarylamine derivatives bearing an ureido pyrimidinedione moiety were synthesised and formed dimers in the solid state and solution through quadruple hydrogen-bonds. These bonding interactions stabilized the mixed-valence states of the tri-arylamine dimers without any electronic coupling between ...
15-10-2014 | Kazuto Hatakeyama; Mohammad Razaul Karim; Chikako Ogata; Hikaru Tateishi; Takaaki Taniguchi; Michio Koinuma; Shinya ..., Chemical Communication, 2014
Graphene oxide (GO) walled channels filled by sulfate ions exhibit an optimized proton conductivity, which is higher than the proton conductivity of all other forms of GO. The sulphate ion increases the water absorbing capacity and hydrogen bond reformation process in GO.
09-10-2014 | Thorfinnur Gunnlaugsson; Komala Pandurangan; Jonathan A Kitchen; Salvador Blasco; Francesca Paradisi, Chemical Communication, 2014
The synthesis and characterisation of novel aryl-pyridyl ureas is described, which form self-assembly structures via extended hydrogen bonding and π−π interactions in the solid state, and in selected cases, forms supramolecular organo- or hydrogels with antimicrobial properties against ...
09-10-2014 | Shuang Cao; Yong Chen; Chuan-Jun Wang; Ping He; Wen-Fu Fu, Chemical Communication, 2014
Monodispersed nickel phosphide (Ni2P) nanoparticles were for the first time applied to photocatalytic hydrogen evolution from lactic acid aqueous solution under visible light LED irradiation using CdS nanorods as a photosensitizer. The system exhibited high photocatalytic hydrogen-generating ...
09-10-2014 | Koroush Sasan; Qipu Lin; ChengYu Mao; Pingyun Feng, Chemical Communication, 2014
A new biomimetic heterogeneous photocatalyst ([FeFe]@ZrPF) has been synthesized through the incorporation of homogeneous complex 1 [(í-SCH2)2NC(O)C5H4N]–[Fe2(CO)6] into the highly robust zirconium-porphyrin based metal–organic framework (ZrPF). The immobilized biomimetic [Fe2S2] catalyst inside ...
