2,6-(N,N-Diurea)-Pyridine Containing Periodic Mesoporous Organosilicas Materials |
| 초록 |
We have synthesized 2,6-(N,N-diurea)-pyridine containing periodic mesoporous organosilicas (PyDUPMOs) materials with intra framework urea groups with nitrogen chelating ligand (Pyridine-Diurea) via a surfactant-templated route by co-condensation of an organosilane precursor and tetraethoxy orthosilicate. The final materials were investigated in detail by means of XRD, TEM, solid state NMR, FT-IR and N2 adsorption, in order to study the effect of diurea silane group concentration on their mesoscopic order and pore structure. The material possesses hexagonal pores with a high degree of uniformity and shows long-range order as confirmed by the measurement of powder X-ray diffraction and N2 adsorption isotherms. The successful synthesis of the organosilane precursor was confirmed by liquid 1H & 13C NMR and FT-IR spectroscopic analysis. |
