The authors would like to add the following two recent references to this paper:
K. R. J. Thomas, M. Velusamy, J. T. Lin, S.-S. Sun, Y.-T. Tao and C.-H. Chuen, Chem. Commun., 2004, 2328;

These two references describe the synthesis and properties of some benzothiadiazole-thiophene-based red OLED materials. However, the authors would like to point out that there are differences in both chemical structure and the EL properties between the authors’ bisindoles containing a benzothiadiazole unit and the compounds reported in the two references. In particular, as the authors stated in this paper, the synthesis procedure for bisindole-benzothiadiazole red OLED materials is facile without using more synthetic steps and an expensive tin agent with strong toxicity. Moreover, this paper broadened out the application area of bisindole compounds, which are known as drugs.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
