中文摘要	a new periodic mesoporous organosilica material (named as bpd-pmo) was synthesized through co-condensation of bis(triethoxysilyl) ethane (btee) and a synthesized silsesquioxane precursor 4,4'-bis [si(oet)(3)(ch2)(4)]-2,2'-bipyridine (bpd-si) in the presence of cetyltrimethylammonium bromide (ctab) surfactant as template. subsequently, three near-infrared (nir) luminescent pmo hybrid materials (named as ln(dbm)(3)bpd-pmo, ln er, nd, yb) covalently linked with lanthanide complexes were successfully prepared via a ligand exchange reaction. the materials were characterized by xrd, n-2 adsorption-desorption isotherms, sem, and fluorescence spectra, and the corresponding luminescent decay analyses were recorded. of importance here is that the excitation spectra of the ln(dbm)(3)bpd-pmo extend to the visible-light range. following the visible-light excitation, the ln(dbm)(3)bpd-pmo materials show the characteristic nir-luminescence of the corresponding ln(3+) ions. the good nir-luminescence properties of the ln(dbm)(3)bpd-pmo with the visible-light excitation would extend the potential applications of the pmo matrix to the nir optical field.
