“…Both molecules catenanes and rotaxanes and their synthesis are described elsewhere [3][4][5][6][7][8][9]. We were choose different kind of rotaxane: fumrot -fumaramide [2]rotaxane, rotaxane -benzylic amide [2]rotaxane where the phenil group of the stoppers were replaced by the aliphatic chains and thread -thread of rotaxane.…”

Catenanes and rotaxanes are a new class of functional organic molecules compose from mobile parts and designed for use in various types of practical applications. They can exhibit interesting third order nonlinear optical properties. In this paper we will present and discuss study of the rotational contributions to the cubic susceptibility as observed by polarization dependent degenerate four wave mixing experiments on solutions of selected catenanes and rotaxanes.

“…Catenanes and rotaxanes are mechanically interlocked molecules composed of moving parts. − They are organic systems which offer unique architectural and structural properties and have attracted great attention as promising candidates for applications in photonics, particularly in all optical and electrooptical switching . The catenanes are formed by interlocking two or more macrocycles.…”

“…Both catenanes and rotaxanes can be functionalized and their physicochemical properties can be tailored by derivatization. They can also be processed into good optical quality thin films by vacuum sublimation . The linear and nonlinear optical properties of these films were studied by various techniques and the results of these investigations are presented and discussed in this report.…”

“…[1][2][3] They are organic systems which offer unique architectural and structural properties and have attracted great attention as promising candidates for applications in photonics, particularly in all optical and electrooptical switching. 4 The catenanes are formed by interlocking two or more macrocycles. In the case of rotaxanes, one or more macrocycles are locked onto a thread by two bulky stoppers located at both ends of the thread (e.g., two phenyl rings in fumaramide [2]rotaxane).…”

Surface Enhanced Second Harmonic Generation from Macrocycle, Catenane, and Rotaxane Thin Films: Experiments and Theory

et al. 2006

Surface enhanced second harmonic generation (SE SHG) experiments on molecular structures, macrocycles, catenanes, and rotaxanes, deposited as monolayers and multilayers by vacuum sublimation on silver, are reported. The measurements show that the molecules form ordered thin films, where the highest degree of order is observed in the case of macrocycle monolayers and the lowest in the case of rotaxane multilayers. The second harmonic generation activity is interpreted in terms of electric field induced second harmonic (EFISH) generation where the electric field is created by the substrate silver atoms. The measured second order nonlinear optical susceptibility for a rotaxane thin film is compared with that obtained by considering only EFISH contribution to SHG intensity. The electric field on the surface of a silver layer is calculated by using the Delphi4 program for structures obtained with TINKER molecular mechanics/dynamics simulations. An excellent agreement is observed between the calculated and the measured SHG susceptibilities.
