摘要

N-3-Cyanobenzylcinchonidinium bromide (N-3-CBC) (1) as a homochiral spacer reacts with CuBr under hydrothermal conditions, resulting in the formation of discrete CuBr2(N-3-CBC)(CH3OH) (2). Similarly, a chiral phase transfer catalyst (CPTC) building block, [bis(N,N'-cinchoninium)-p-xylene dibromide (NCXD)] (3), was employed as an asymmetric bridging linker to construct a one-dimensional (ID) photoluminescence coordination polymer, Cu2Br4(NCXD)(H2O)(3) (4). Compounds 2 and 4 exhibit bright luminescent emissions at room temperature upon irradiation by UV light. Crystal data for 2: space group P2(1) with a = 8.3596(7) angstrom, b = 20.1496(17) angstrom, c = 8.7591(8) angstrom, alpha = gamma = 90 degrees, beta = 110.517(2)degrees, V = 1381.8(2) angstrom(3), Z = 2, R1 [I > 2 sigma(I)] = 0.0539, wR2 (all) = 0.1336, Flack value 0.011(14); crystal data for 4: space group P2(1)2(1)2(1) with a = 21.4407(18) angstrom, b = 24.779(2) angstrom, c = 9.2166(8) angstrom, alpha= gamma = 90 degrees, V = 4896.6(7) angstrom(3), Z = 4, R1 [I > 2 sigma(I)] = 0.1051, wR2 (all) = 0.2760, Flack value 0.11(3).
