Organic/inorganic hybrid solid IHM-2-N₃provided with an azide function, and method for manufacturing same

摘要

The invention describes a crystallized hybrid solid with an organic-inorganic matrix, of a three-dimensional structure, containing an inorganic network of indium-based metal centers that are connected to one another by organic ligands that consist of the entity —O2C—C6H3—N3—CO2—. Said solid is called IHM-2-N3 and has an X-ray diffraction diagram as given below.

1. A IHM-2-N3 crystallized hybrid solid with an organic-inorganic matrix, of a three-dimensional structure, containing an inorganic network of indium-based metal centers that are connected to one another by organic ligands that consist of the entity —O2C—C6H3—N3—CO2— (N3-bdc ligand), whereby said solid exhibits an X-ray diffraction diagram that includes at least the lines that are recorded in the table below:2 Theta (°)dhkl (Å)I/Io4.6818.87mf8.1210.88ff8.959.87ff9.379.43FF11.787.51ff11.947.41f12.437.11ff14.086.28ff14.746.00ff16.345.42f16.955.23ff17.455.08ff18.014.92ff18.804.72mf18.964.68f21.034.22ff23.533.78ff23.823.73ff25.043.55ff26.453.37ff26.683.34ff27.413.25ff28.333.15ff28.613.12ff29.743.00ff31.242.86ff32.352.77ff34.202.62ff35.472.53ff38.062.36ff41.712.16ff42.022.15ff42.742.11ff43.042.10ff45.921.97ff54.571.68ffwhere FF = Very High; F = High; m = Medium; mf = Medium Low; f = Low; and ff = Very Low, with the relative intensity I/Io being provided in relation to a relative intensity scale where a value of 100 is assigned to the most intense line of the X-ray diffraction diagram: ff < 15; 15 ≦ f < 30; 30 ≦ mf < 50; 50 ≦ m < 65; 65 ≦ F < 85; and FF ≧ 85, and whereby H—N MR analysis confirms the presence of an N3 azid group on an aromatic cycle of a deprotonated terephthalic ligand: 8=7.73-7.83 ppm, m, 3H, ArH, 3 protons leading to the detection of the multiplet corresponding to 3 protons carried by the aromatic cycle of the (N3-bdc) ligand.
