Abstract

The IR-ATR, IR transmittance and Raman spectroscopy techniques were used in monitoring the immobilization of newly synthesized compounds (4-O-acetyl ferulato)triphenyltin(IV) and (fenoprofenato)tributyltin(IV), showing anticancer activity, on MCM-41 and SBA-15 mesoporous silica nanostructures (MSN). The IR analysis of the synthesized tin(IV) compounds proved a monodentate binding of the carboxylic group to the Sn atom, using the splitting of the ν(COO) band in the IR spectrum. The IR-ATR spectra of the synthesized MSN were used to check the porosity of the synthesized materials on the basis of the changes of the Si-OH(H₂O) and Si-O stretching vibration band profile. The immobilized organotin(IV) compounds in both MSN were analyzed and the success of the immobilization was monitored and discussed through the changes in the IR and Raman spectra.
