The present invention concerns materials consisting in a porous and structured network, this network being at least in part formed by Si atoms, or Si atoms and metal atoms, linked to each other's via siloxy bonds, the amount of radical ranging from 0.50 to 0.03 mmol of radical per gram of material, and in that the network is formed with a sol-gel step using an organosilane for the introduction of the organic molecules allowing their regular distribution within the porous structured material. The invention also concern a process for the preparation of such material and a method of analysis by Nuclear Magnetic Resonance (NMR) of an analyte wherein it uses dynamic nuclear polarization generated with a material according to the invention.
