The formation mechanism of MCM-41 was investigated by in situ EPR spectroscopy using spin-probes and the location of the spin-label in the organic-inorganic interfaces was established using electron spin echo envelope modulations. It is found that the EPR line-shapes is highly sensitive to the progress of the reaction, and the mobility of the spin-probe is significantly restricted as the silicate ions polymerize at the interface. The long range ordering is established rather rapidly, while the condensation process is significantly slower.
