Multiphoton harvesting metal–organic frameworks

Usually multiphoton harvesting property exhibited by the organic molecules in the solution, is quenched in the solid state due to aggregation. However, efficiently luminescent materials in the solid-state form are highly preferable in many photonic applications such as upconversion lasing and light emission due to a higher resistant to photobleaching. By rational choice of ligands with high second hyperpolarizability, MOFs with large nonlinear optical response (up to direct absorption of four photons at 1500 nm) has been reported for the first time by Hong Sheng Quah, Weiqiang Chen, Martin K. Schreyer, Hui Yang, Ming Wah Wong, Wei Ji, and Jagadese J. Vittal in the recent issue of Nature Communications (Vol. 6, Article No. 7954, 2015, doi:10.1038/ncomms8954).

Singaporean Inorganic Chemistry Symposium 2015

The inaugural Singaporean Inorganic Chemistry Symposium (SICS2015) was held at University Town on the 29th of July, 2015. The symposium featured researchers from over thirteen inorganic based research groups from both the NUS Department of Chemistry and the NTU Division of Chemistry and Biological Chemistry in attendance. A wide range of inorganic research was showcased by eleven speakers, varying from medicinal chemistry to catalysis to fundamental main group chemistry. ‘Best Speaker’ awards were presented to Mr Kennard Gan (NTU), Ms Shi Xiaoyan (NTU) and Mr Kelvin Lim (NUS). The SICS2015 organising committee would like to thank the NUS Department of Chemistry for their support in organising this event. More photos.

Energy-Based Molecular Fragmentation Methods

The review covers the state-of-the-art of energy-based molecular fragmentation methods of which both authors have made significant contributions. The defining characteristic of an energy-based molecular fragmentation method is that the molecule (also cluster of molecules, or liquid or solid) is broken up into a set of relatively small molecular fragments in such a way that the electronic energy of the full system is given by a simple linear combination of the energies of these fragment molecules. The successful application of the method enables accurate solution of the Schrodinger equation for molecules the size of proteins. Reported by Associate Professor Ryan P A BETTENS group.

Temporal full-color tuning through non-steady-state upconversion
Nature Nanotechnology

Assoc Professor LIU Xiaogang group reported that producing luminescence materials with tunable emission colors that can be applied for high quality displays is a very difficult task. Especially, it is challenging to develop light-responsive materials that are possible to produce any desired colors in a broad spectrum range on demand through the use of a simple external stimulus. Now they have achieved this goal by exploiting a novel concept, non-steady-state upconversion, based on the design and synthesis of lanthanide-doped core-shell upconversion nanomaterials. The emission color of the core-shell upconversion nanocrystals was turned by adjusting the pulse width and intensity of near-infrared laser excitations. R. Deng, F. Qin, R. Chen, W. Huang, M. Hong, X. Liu, “Temporal full-color tuning through non-steady-state upconversion, ” Nature Nanotechnology, 2015, 10, 237-242. Read More.
