Dynamical Behavior and Second Harmonic Generation Responses in Acido-Triggered Molecular Switches
Second-order nonlinear optical molecular switches are systems displaying marked variations of their second harmonic generation (SHG) responses upon external stimulation. In this article, we combine a multiscale computational method and experimental characterizations to provide a full description of the SHG responses of molecular switches built from the association of the indolino-oxazolidine unit to a bithiophene donor. In chloroform solutions, the addition of trifluoroacetic acid triggers the switching from a neutral closed form to a protonated open form, making an ion pair with the trifluoroacetate counterion and induces a strong enhancement of the SHG responses. The numerical simulations (i) evidence how the large and rapid thermally induced geometrical fluctuations lead to broadening the SHG responses distributions, making even difficult the determination of their sign, (ii) rationalize the variations of these responses as a function of the closure/opening of the oxazolidine ring and of the nature of its chemical substitution, and (iii) call into question common assumptions employed when analyzing the experimental SHG responses.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 84793-24-8 help many people in the next few years. Computed Properties of C16H19NO5.
