Polymeric double-anion templated Er48 nanotubes

3 January, 2014 - 14:17

Chem. Commun., 2014, 50,1113-1115
DOI: 10.1039/C3CC46779A, CommunicationMingyan Wu, Feilong Jiang, Daqiang Yuan, Jiandong Pang, Jinjie Qian, Shaeel A. AL-Thabaiti, Maochun Hong
A polymeric tube-like Er48 complex has been synthesized and structurally characterized, in which two types of anions, i.e. Cl- and NO3-, template the formation of Er18 wheels and Er12 rings through hydrogen bonding, respectively.

Topological morphology conversion towards SnO2/SiC hollow sphere nanochains with efficient photocatalytic hydrogen evolution

3 January, 2014 - 14:17

Chem. Commun., 2014, 50,1070-1073
DOI: 10.1039/C3CC47790H, CommunicationXunfu Zhou, Yingju Liu, Xin Li, Qiongzhi Gao, Xiaotang Liu, Yueping Fang
Novel SnO2/SiC HSNCs were synthesized by topological morphology conversion of SnO2@C CSNCs through a vapour-solid reaction. Evaluation of the SnO2/SiC HSNCs for the generation of hydrogen revealed that they exhibit excellent catalytic activity and durability.

Three component assemblies by orthogonal H-bonding and donor-acceptor charge-transfer interaction

3 January, 2014 - 14:17

Chem. Commun., 2014, 50,1064-1066
DOI: 10.1039/C3CC47376G, CommunicationHaridas Kar, Suhrit Ghosh
Three component supramolecular assemblies from a mixture of an aromatic donor (D), acceptor (A) and external structure directing agent (ESDA) are achieved by orthogonal noncovalent interactions involving two different types of H-bonding and alternate D-A stacking.
