The influence of structural variations of phenyl‐hydrazones and stilbazium salts on monolayer behaviour and second‐harmonic generation in LB‐monolayers is discussed. In contrast to the stilbazium salts the variation of the substituents of the phenylhydrazones does not influence the absorption maximum of the dyes in resonance enhancement of the nonlinearity. This allows a direct comparison of the substitution pattern on SHG.
