Benzotriazol-based structure assemble directed by transition metals
Tóm tắt
Two coordination polymers, namely [Mn(L)2(H2O)2]n (1) and [Cd2(L)4(H2O)4]n (2) {HL = (benzotriazol-1-yloxy)-acetic acid}, have been synthesized and characterized by single-crystal X-ray diffraction as well as with infrared spectroscopy and elemental analysis. The results reveal that CP1 has 1D double chain structure, while CP2 features a 1D infinite chain structure. Additionally, there both exist O–H···O and O–H···N hydrogen bonds in CP1 and CP2, forming 3D supramolecular structures, respectively. UV-vis absorption spectra of CP1, and photoluminescence property of CP2, have been examined in solid state at room temperature. The result on optical energy gap of 2.80 eV indicates that CP1 is a potential semiconductive material.
