The reaction was carried out by mixing of the 9H carbazoles derivatives with bromo esters and potassium hydroxide using DMF as solvent under microwave irradiation without catalyst. The optimized experiment conditions were 48 min irradiation time and 375 W microwave power. The required range of molar ratio of KOH to substituted carbazole was 35. The biological activities of some compounds have been tested. They have medium to weak antimicrobial activities.展开更多

It has been characterized by IR, UV, TGA, Elemental analysis and X-ray diffraction analysis. The crystal belongs to triclinic system, P1 space group. The Crystallographic data are: a = 0.702 7(14) nm, b = 0.828 95(17) nm, c = 10.225(2) nm, α = 95.02(3)°, β = 91.45(3)°, γ = 99.85(3)°. The crystal structure data indicate that the Zn(Ⅱ) ion was coordinated with the four nitrogen atoms of two dafo and two oxygen atoms of two coordination water molecules, respectively. The complex has a one-dimensional chain structure, which is formed by hydrogen bonds.展开更多
