In this paper we report on the second harmonic generation properties of non-centrosymmetrical Langmuir-Blodgett films built from mixtures of push-pull carotenoids with ω-tricosenoic acid or amphiphilic cyclodextrin. The effects of the carotenoid as well as of the diluent on the orientational order have been studied both in monolayers and alternate active-passive multilayers.
