Fabrication of high performance, multi-layered phosphorescent organic light-emitting diodes (PhOLEDs) is often done by vacuum deposition of small organic molecules which can be a lengthy and costly process. Solution processing (layers can either be coated or printed from solution) is a more viable technique in terms of cost. However when it is used to make multilayered devices the lower layer can be affected by the solvent from upper layers due to inter-miscibility. It would be better to have electron and hole transporter materials together in a single layered device.

Yan Huang, Zhiyun Lu and colleagues have reported two novel orange iridium(III) complexes. The complexes were synthesized by modifying the phenyl moiety of the parent complex, (bt)₂Ir(acac) (bt = phenylbenzothiazole, acac = acetylacetonate). The new complexes have good thermostability and film amorphism meaning that they were able to be tested in a solution-processed single layer PhOLED. Both complexes demonstrated higher luminescence and efficiency than the parent complex. The improved characteristics of the two new Ir(III) complexes mean that they are promising candidates for use in low cost fabrication of PhOLEDs for large area displays.

Congratulations to Philip Power, who has been awarded the inaugural Dalton Distinguished Lectureship in recognition of his work on transition metal and main group chemistry.

Supported by Dalton Transactions, this lectureship is awarded yearly to an outstanding senior researcher in the field of inorganic chemistry. Besides providing recognition for high quality chemistry research, it also facilitates interaction between researchers in different institutions.

Philip will be presenting his lecture at University of California, Berkeley on the 7th February 2014.

Philip received his B.A. from the University of Dublin in 1974, and commenced on his PhD research at the University of Sussex under M.F. Lappert. After graduating in 1977, he spent two years working as a postdoctoral researcher in Stanford under R.H. Holm. In 1981, he started a faculty position at University of California, Davis, where he is currently a Professor.

We would like to congratulate Trevor Hayton, who has been awarded the 2013-2014 Dalton Lectureship, in recognition of his work on actinides, especially his ground-breaking work on f-element chemistry.

This lectureship, sponsored by Dalton Transactions, aims to enhance communication between the best researchers, and is awarded yearly to an outstanding young investigator in the general field of inorganic chemistry.

Trevor will be presenting his lecture at University of California, Berkeley in early 2014, where he will also be spending time with the faculty, postdocs and students.

Trevor Hayton grew up in Surrey, British Columbia. In 1998, he received his B.Sc. in Chemistry from the University of British Columbia, whereupon he began his Ph.D. research, also at UBC, under the direction of Peter Legzdins. After graduating in 2003, he began a postdoctoral fellowship at Los Alamos National Laboratory, working under the direction of James M. Boncella. In 2006 he started a faculty position at University of California, Santa Barbara, where he is currently an Associate Professor.
