Abstract : Sol-gel synthesis approaches have enabled researchers to design composite-type materials where dopant molecules which carry out various types of chemical reactions are trapped in the nanopores of the host material. Dopant molecules have been shown to undergo chemical, photochemical and electrochemical reactions in the pores of sol-gel matrices with specific examples including complexation reactions, redox reactions, catalysis, protonation-deprotonation, isomerization and ion/electron transfer. The interconnected pore network of the xerogel or aged gel structure ensures that the molecules are responsive to the outside environment, yet the molecules are also trapped within the inorganic matrix which confines molecular motion and prevents their being leached from the matrix. jg p.1
