Article: Reports on chemistry findings from F. Balzer and co-researchers provide new insights.

"Results of a systematic study of the growth of blue-green light-emitting 2,5-di-4-biphenylthiophene (PPTPP) molecules on the (001) faces of the sheet silicates muscovite an phlogopite mica are reported. This includes morphology, crystallography, and optical properties," scientists writing in the journal Chemistry of Materials report.

"It is shown that small changes in the choice of the substrate,lead to distinctly different growth behavior. On muscovite, a commensurate wetting layer of lying molecules is initially formed with subsequent formation of clusters; which assemble into mutually parallel nanowires. The wires grow along a <110> muscovite direction, having the ...
