General description

Titanium(IV)isopropoxide is a high-purity, colorless to yellowish liquid with a pungentodor. It is a colorless to yellowish liquid with a pungent odor. This compoundis used in various applications such as producing high-quality titanium dioxidefilms on glass and in electronics to produce thin-film transistors. It is alsoused in the production of specialty polymers, ceramics, and in organicsynthesis.

Application

Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.

From Form to Function: Molding Porous Materials in Three Dimensions by Colloidal Crystal Templating

Research involving reactive silicone chemistry has focused on the production of pure silicon and hybrid materials, hydrosilylation, ring-opening and atom transfer polymerizations, polymerizations with controlled stereochemistry, and condensation reactions.

Mesoporous materials, such as aerogels, offer advantages for practical hydrogen storage. They have large surface areas, open porosity, small pore sizes, and the ability to coat the surface with one or more compounds.
