The effects of a series of small structural changes to (S)-5-nitro-N-(1-phenylethyl)pyridin-2-amine
on its solid state non-linear optical properties, including the phenomenon
of rotating dielectric axes, have been investigated. Installation of a methyl
group in the 3-position of the heterocyclic ring or at the amino nitrogen
atom gave the most promising materials, though neither of these materials
showed rotating dielectric axes. Details of the crystal structure analyses
of a family of these compounds illustrate the delicate interplay between molecular
conformation and intermolecular interactions in determining the packing arrangements.
