Design and synthesis of Alq3-functionalized SBA-15 mesoporous material

A luminescent organic molecule aluminum tris(8-hydroxyquinoline) (Alq3) has been successfully introduced in the pores of amino-functionalized mesoporous SBA-15 (APS-SBA-15). An obvious blue-shifted photoluminescence (PL) of Alq3 was observed. In the pores of APS-SBA-15, the Alq3 organic molecules exhibited efficient and intense PL as monomers and the emission intensities increased with increasing Alq3 concentration.
