| Abstract：2-(1-Octyl-1H-benzo[d]imidazole-2-yl)phenol(L) and its zinc complex(I) were prepared from salicylic acid, o-phenylenediamine and 1-bromooctane. Their structure and properties were characterized by IR, UV, 1H NMR, elemental analysis and so on. The luminescent properties of compound L and compound I were evaluated. Experimental data indicated that their maximum emission wavelength were 392 nm, 450 nm and 412 nm, respectively. The crystal structure of compound I was measured by X-ray single crystal diffraction and data analysis indicated that the compound I belonged to a monoclinic structure with a space group C2/c(a=30.424 4(15)?魡, b=9.794 4(4)?魡, c=17.896(1)?魡, V=5296.6(5)?魡3, Z=8, ρ=1.270 5 g·cm-3, μ=1.149 mm 1, F=199 7.5, R=0.088 5, wR=0.222 9, GOF=1.035). The thermogravimetic data analysis of compound I indicated that it was thermostable at room temperature. |
