The　Fe3+-modified　1,　8-naphthalic　anhydride　(Fe-NA)　was　prepared,　and　thereafter　successfully　grafted　on　the　mesoporous　surface　of　bimodal　mesopores　material　(BMMs)　by　post-synthesis　method.　The　influence　of　various　parameters,　including　amount　of　Fe3+　ion,　various　solvents,　different　concentrations　and　loadings　of　FC-NA　on　the　fluorescence　behavior　of　resultant　hybrid　materials　(FC-NA　grafted　BMMs)　was　investigated,　and　then　its　fluorescence　properties　were　compared　to　the　parent　FC-NA.　Meanwhile,　their　structural　properties　and　photoluminescence　performances　were　investigated　using　various　characterizations　XRD,　TEM,　SEM,　SAXS,　FT-IR,　TGA,　ICP-OES,　elemental　analysis,　N-2　adsorption-desorption　isotherms,　and　fluorescence　measurement.　The　results　showed　that　the　mesoporous　structural　integrity　was　remained　intact　after　introduction　of　FC-NA　in　the　mesoporous　channels　of　APTES-BMMs.　Particularly,　SAXS　patterns　revealed　the　mass　fractal　dimension　of　the　hybrid　FC-NA@BMMs　were　gradually　increased　with　increasing　loaded　amount　of　FC-NA,　and　resulted　in　the　uneven　distribution　and　self　similarity　fractal　features.　The　fluorescence　profiles　exhibited　the　occurrence　of　red-shifts　and　then　blue　shifts　of　characteristic　peak　with　increasing　grafted　FC-NA　amount.　These　shifts　demonstrated　a　highly　aggregation　on　the　amine-modified　mesoporous　surface　of　APTES-BMMs　when　the　obtained　mass　ratio　of　FC-NA/AP-BMMs　was　lower　than　0.2,　whereas　a　uniform　monodispersion　distribution　was　observed　when　the　mass　ratio　got　higher　than　0.2.　The　obtained　functionalized　mesoporous　materials　with　enhanced　fluorescence　intensity　have　a　potential　application　in　drug　sustained/controlled　delivery　systems.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
