The　organic-inorganic　mesoporous　materials　(ZZnBMMs)　were　successfully　synthesized　by　Zn-grafting　into　the　surface　of　bimodal　mesoporous　silicas　(BMMs)　via　covalent　bond,　and　then　immobilization　of　(2S,2＇S)-N,N＇-([2,2＇-bipyridine]-3,3＇-diyl)bis(pyrrolidine-2-carboxamide)　(Z)　onto　the　Zn-modified　BMMs　through　coordination　method.　The　influences　of　washed　parameters　such　as　various　solvents　(petroleum　ether,　CH2Cl2,　CH3OH,　or　DMSO)　and　pretreated　temperature　on　the　structural　stability　of　obtained　ZZnBMMs　were　investigated　thoroughly,　which　were　extensively　characterized　by　means　of　XRD　patterns,　UV-vis　and　FT-IR　spectra,　N-2　sorption　isotherms,　SEM　images,　and　SAXS　patterns.　The　results　showed　that　petroleum　ether　could　be　acted　as　optimum　solvent　for　washing　ZZnBMMs　when　pre-treated　temperature　was　around　20　degrees　C.　The　SAXS　patterns　evidently　demonstrated　that　ZZnBMMs　before　and　after　washing　presented　the　fractal　features,　suggesting　their　surface　roughness　and　structural　irregularities,　in　which,　the　mass　fractal　(D-m)　values　were　gradually　decreased　along　with　not　only　the　increased　polarity　of　used　solvents　(petroleum　ether,　CH2Cl2,　CH3OH,　and　DMSO),　but　also　enhanced　washing　temperature　of　from　20-60　degrees　C　and　prolonged　time　of　from　4-168　hrs.　Furthermore,　the　ZZnBMMs　as　a　heterogeneous　catalyst　for　asymmetric　aldol　reaction　exhibited　the　recycled　(at　least　6　times)　catalytic　performances　with　high　efficiency　(around　92.1%　yield)　and　good　selectivity　(up　to　68%　ee).
