Synthesis, characterization and optical property of a new two-dimensional (2-D) copper halide coordination polymer [image(1,10-phen)4][image] (phen = phenanthroline)

The hydrothermal reaction of CuBr2, CuBr and 1,10-phen gives birth to a 2-D coordination polymer [image(1,10-phen)4][image] (1), consisting of the unique image chains linked by the stepped-cubane copper(II)-hydroxo clusters image as the bridges. Compound 1 possesses high thermal stable. The non-linear optical property of 1 was studied, and the compound exhibits the reverse saturable absorption (α2 = 0.80 × 10−11 m W−1) and self-defocusing performance (n2 = −1.55 × 10−18 m2 W−1).
