We　report　on　the　synthesis　of　luminescent　hybrid　mesoporous　materials　(LHMS)　by　covalently　anchoring　2-[3-(triethoxysilyl)　propyl-1H-Benz　[de]isoquinoline-1,　3(2H)-dione　to　bimodal　mesoporous　materials　(BMMs)　through　postsynthesis　methods.　The　resulting　samples　were　characterized　by　powder　X-ray　diffraction　(XRD).　Fourier　transform　infrared　spectroscopy　(FT-IR),　N-2　adsorption/desorption　isotherms,　transmission　electron　microscopy　(TEM),　Si-29　NMR　analysis,　elemental　analysis,　and　fluorescence　measurements.　The　results　revealed　that　luminescent　organic　molecules　have　been　successfully　introduced　into　the　pore　channels　of　BMMs　without　disrupting　the　structure,　whereas　the　ordering　degree　of　BMMs　framework　decreased　after　functionalization.　The　obtained　materials　(LHMS-10)　showed　excellent　luminous　performance,　and　the　emission　peak　shifted　to　a　lower　wavelength　in　comparison　with　that　of　pure　luminescent　dyes　(from　464　to　454　nm)　because　of　the　polarity　of　the　silica　matrix.　And　the　amount　of　fluorescence　molecule　had　some　influence　on　the　luminescence　behavior,　which　was　also　investigated　and　discussed.　It　can　be　concluded　that　the　fluorescence　properties　of　the　dye　molecule　can　be　controlled　at　will　by　the　loading　amount.　(C)　2011　Elsevier　B.V.　All　rights　reserved.
