Chirooptical control of liquid crystalline textures containing chromium complex by irradiation of circular polarized light

A cholesteric texture was induced in the liquid crystal (a mixture of N-(4- ethoxybenzylidene)-4-n-alkylanilines doped with (R)-(+)-1,1-bi-2-naphthol a nd racemic chromium tris(3-butyl-2,4-pentanedionate) (Cr(3-Buacac)(3)) by t he irradiation of right circular polarized light (r-CPL) and resulting chir oselective photoinversion of Cr(3-Buacac)(3). After irradiation of left cir cular polarized light (l-CPL), the cholesteric fingerprint texture was eras ed.
