We describe an evaporation-induced self-assembly method for incorporating Ti into framework of ethane-bridged periodic mesoporous organosilica (PMO). The X-ray diffraction (XRD), transmission electron microscopy (TEM), solid-state Si-29 and C-13 nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and UV-vis spectroscopy were used to elucidate the optical and structural properties of Ti-incorporated PMO materials. The degree of nnesopore ordering and the structural properties were found to be dependent on the loading of Ti into the framework of PMO materials, as confirmed by XRD, and surface structural properties. UV-vis spectra also support the incorporation of Ti into framework of PMO. TEM analyses suggested the formation of mesopores for the pure PMO and Ti-incorporated PMO samples. The solid-state NMR and FT-IR spectra have confirmed the presence of organic fragment in the final PMO framework.
