Abstract

original image

Azobenzene-containing crosslinked ferroelectric liquid-crystalline polymers offer unique opportunities for reversible, high-contrast switching of a second-order nonlinear optical response in the solid state. Atsushi Shishido and co-workers show on p. 6410 that this is achieved by reversibly controlling non-centrosymmetric chromophore alignment through two-photon isomerization of azobenzene molecules.
