在这篇文章中，我们报告了成功的合成一类新的周期性介孔有机硅（PMOs）与脲桥有机硅前体在酸催化和无机盐辅助条件下。大孔杂化材料具有有序的介观结构，具有均匀的孔径分布、优异的厚骨架壁、热稳定性和特定的官能团。通过FTIR光谱、（13）C交叉极化魔角旋转（CP MAS）NMR光谱和（29）Si MAS NMR光谱表征了介孔有机硅的组成。
In this article we report the successful synthesis of a new class of periodic mesoporous organosilicas (PMOs) with a urea-bridged organosilica precursor under acid-catalyzed and inorganic-salt-assisted conditions. The large-pore hybrid materials have an ordered mesostructure with uniform pore size distributions, excellent thick framework walls, thermal stability, and specific functional groups. The composition of the mesoporous organosilicas was characterized by FTIR spectroscopy, (13)C cross-polarization magic-angle spinning (CP MAS) NMR spectroscopy, and (29)Si MAS NMR spectroscopy.
