摘要：Coumarin derivative encapsulated in various mesoporous sieves was prepared by impregnation method. The effects of pore size and Ti-containing amounts on the fluorescence properties were investigated. High dispersion of the dye molecules could be realized on the composite of mesoporous sieves, and the electron transfer from the excited dye molecule to titanium oxide occurred in the composite.
