Abstract	Three chiral Schiff base (bis(N-R-2-phenylpropyl-3,5-dibromosalicydenaminato)) nickel(II), copper(II), and zinc(II) complexes and their hybrid materials with azobenzene (AZ) have been investigated by means of electronic and CD (circular dichroism) spectra in PMMA matrix. Due to Weigert effect, metal complexes as well as AZ increased their optical anisotropy after linearly polarized UV light, which was confirmed by with polarized electronic and IR spectra. Furthermore, we have measured CD spectra before and after circularly polarized UV light. We have found that supramolecular chirality resulting from molecular arrangement could be induced for rigid Zn(II) complex was larger than that of flexible Ni(II) or Cu(II) complexes.
