In order to investigate the cone's spectral responses under different conditions for different aged observers with normal color vision, nine color patches with different hue angles distributed uniformly on the CIELAB color space were prepared, and the 27-35 observers were organized to carry out color matching experiments on a monitor to match the nine(More)
In the title compound, C(14)H(10)O(6)S(2), the dihedral angle between the planes of the two phenyl-ene rings is 55.9 (1)°. Both hydr-oxy groups form intra-molecular hydrogen bonds; however, one of them also engages in inter-molecular hydrogen bonding. In the crystal, mol-ecules are connected into helical chains by O-H⋯O hydrogen bonds. The crystal studied(More)
The title Cd(II) coordination polymer, catena-poly[[{1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane}cadmium(II)]-μ-benzene-1,3-dicarboxyl-ato], [Cd(C(8)H(4)O(4))(C(30)H(28)N(6))](n), was obtained by reaction of CdCO(3), benzene-1,3-dicarboxylic acid (H(2)btc) and 1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane (L). The Cd(II) cation is(More)
