Oxygen sites in ethane-bridged and phenylene-bridged PMOs prepared using neutral templates in acidic conditions are characterized by means of XPS and FTIR spectroscopy of adsorbed pyrrole. Their electron donor ability is observed to be stronger than

Periodic mesoporous organosilicas (PMOs), a relatively new class of mesostructured organic−inorganic hybrid materials already thoroughly characterized as it concerns acidic sites, are studied in the present paper from the viewpoint of electron-rich

Recent joint IR and computational work (Onida et al. J. Phys. Chem B 2005) has allowed a detailed characterization of the isolated silanols at the surface of highly ordered benzene-silica hybrid material. In the present paper, a similar characterizat

Proton-donor ability of carboxylic groups incorporated by co-condensation into SBA-15 and ethane-bridged periodic mesoporous organosilica (PMO) has been studied through IR spectroscopy by dosing ammonia, which forms reversibly COO(-) groups and NH(4)

Bronsted acidity of carboxylic groups on the surface of SBA-15 and periodic mesoporous organosilicas (phenylene-bridged and ethylene-bridged PMOs), incorporated by co-condensation route, is measured as equilibrium constant of the reversible proton-tr

Periodic Mesoporous Organosilicas (PMOs) represent a new class of organic-inorganic hybrid materials suitable for a broad range of applications. In the present contribution iodine vapours were adsorbed on phenylene-bridged PMOs with hexagonal 2D pore

Low-temperature adsorption of carbon monoxide on an ordered periodic mesoporous organosilica (1,4-phenylenesilica PMO) was studied by means of infrared spectroscopy and theoretical calculations on cluster models. Basically, three types of adsorbed CO

Silanol species in phenylene-bridged periodic mesoporous organosilica (PMO), templated via tri-block copolymer Pluronic P123 and thus characterized by large pores and amorphous wall structure, have been characterized by means of FT-IR spectroscopy. I

Herein we report on the mechanism of formation of a hybrid phenylene-bridged hexagonally ordered mesoporous organosilica with crystal-like walls (CW-Ph-HMM). Electron microscopy and X-Ray diffraction studies indicate that the formation of CW-Ph-HMM i
