Abstract

In this paper, according to the principle of site isolation, a ringlike molecule of R1, based on the second-order nonlinear optical chromophore of FTC (Fang's Thermally-Stable Chromophore), was designed and synthesized, in which, the heads and waists of two FTC moieties were locked together through chemical bonds, respectively. Thanks to the ideal spherical structure and good alignment of the two pieces of FTC moieties, R1 exhibited an ultra high nonlinear optical effect with a d33 value of 562 pm V−1 at a wavelength of 1950 nm, which could still retain 80% at a very high temperature of 145 °C.
