抄録
A phosphorescent coordination hybrid has been successfully prepared from silsesquioxane containing phosphine oxide and europium tris β-diketonate. The novel silsesquioxane was synthesized by the sol-gel reaction of corresponding trialkoxysilane obtained by the ene-thiol reaction of allyldipenylphosphine oxide and mercaptopropyltriethoxysilane. Despite the high concentration of the europium complex (50 wt%), the complex was dispersed completely into the silsesquioxane, giving a dense, homogeneous, and transparent hybrid thin film. The luminescence property of this film was also investigated. This hybrid thin film with the embedded europium complex shows bright phosphorescence accompanied with a characteristic sharp spectrum derived from the f-f transition of europium at ambient temperature. It can be concluded that the enhancement of the emission intensity and the branching ratio for the europium complex in the hybrid compared to the europium complex in PMMA is due to the formation of a coordination bond between the europium complex and the phosphine oxide in silsesquioxane.<br>
