This work is the continuation of our previous experimental and theoretical studies aiming at designing efficientnonlinear optical (NLO) switches derived from the benzazolo-oxazolidine core. Here, we report the synthesisand the characterization of the linear and nonlinear optical properties of benzothiazolo[2,3-b]oxazolidineacidochromes by means of hyper-Rayleigh scattering as well as quantum chemical calculations. It is shownthat these new derivatives incorporating a benzothiazole subunit exhibit very high static first hyperpolarizabilityvalues in their acido-generated form. On the basis of previously reported NLO responses of indolino- andbenzimidazolo-oxazolidines, structure-properties relationships within the benzazolo-oxazolidine series areproposed.
