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

Abstract

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). magnified image
