The following papers are very important in the opinion of two referees. They will be published as soon as possible.
2,3,17,18-Tetrahalohexaphyrins and the First Phlorin-Type Hexaphyrins
Tomohiro Higashino and Atsuhiro Osuka*
Convenient preparations of 3,4-dichloropyrrole and 3,4-difluoropyrrole are reported. 2,3,17,18-Tetrahalohexaphyrins were synthesized and meso-reduced hexaphyrins were obtained by reduction of tetrabromo- and tetrachlorohexaphyrin with NaBH4 as the first example of phlorin-type hexaphyrin.
Synthesis, Characterization, and Properties of Few-Layer MoO3
M.B. Sreedhara, H.S.S. Ramakrishna Matte, A. Govindaraj, and C.N.R. Rao*
This study shows that graphene-like nanosheets of MoO3 can be prepared by a variety of chemical methods besides ultrasonication. The prepared few-layer materials exhibit good photocatalytic activity for the degradation of dyes. Composites of MoO3 nanosheets with a conducting borocarbonitride show excellent performance as supercapacitor electrodes.
Transition Metal (Mn, Fe, Co, Ni)-Doped Graphene Hybrids for Electrocatalysis
Rou Jun Toh, Hwee Ling Poh, Zdeněk Sofer, Martin Pumera*
Transition metal-doped graphene hybrids were prepared by exfoliation of metal-doped graphite oxide precursors in either H2 or N2 atmosphere. Characterizations of the materials suggest that the H2 exfoliated materials had higher C/O ratios in general. The electrocatalytic activities of the transition metal-doped graphene hybrids were reflected in an enhancement of the kinetics of oxygen reduction under alkaline conditions, which is important for renewable energy applications such as fuel cells. It was found that hybrid materials exfoliated in N2 atmosphere exhibited greater electrocatalytic activities than those exfoliated in H2 atmosphere.
A Facile Phosphine-Free Method for Synthesizing PbSe Nanocrystals with Strong Optical Limiting Effects
Tian-Ming Wang, Bao Gao, Qiang Wang, Min Zhao, Kai-Bin Kang, Zhu-Guo Xu,* and Hao-Li Zhang*
The current fabrication strategy for colloidal PbSe semiconductor nanocrystals (NCs) frequently involves acutely toxic reagents and tedious reaction procedures, and is plagued by products with poorly controlled size and morphology. Herein, a facile and phosphine-free method for synthesizing PbSe NCs is reported by the reaction of elemental Se and PbCl2 that involves only oleylamine as both ligand and reaction medium. This method results in monodispersed PbSe NCs with well-controlled size and morphology. In addition, the obtained NCs display strong optical limiting effects, and thus hold potential for the development of nonlinear optical devices.
