Donor–acceptor substituted polyenes: Orientation in mono- and multilayers


  • F. E. and C.-P. N. Thank Dr. D. Möbius and G. Overbeck (MPI f. Biophysikalische Chemie, Göttingen) for their help in measuring reflection spectra and fruitful discussions. We thank Prof. G. Wegner, Mainz, for his interest in this work. This work was supported by the Deutsche Forschungsgemeinschaft (SFB 329).


Ordered structures of donor-acceptor substituted polyenes (see Figure, where R'=phenyl or anthryl) formed using the Langmuir-Blodgett technique are reported. The mono- and multilayers have been traansferred to solid supports and their nonlinear optical characteristics examined using angledependent second harmonic generation (SHG).
