摘要
A supramolecular organosilane, 2-(3-(triethoxysilyl)propylaminocarbonylamino)-6-methyl-4[1H]pyrimidinone comprising quadruple hydrogen bonds has been synthesized in one step from commercially available starting materials. The synthesized supramolecular organosilane can be stabilized and phase-separated by dimerization via the linear array of quadruple hydrogen bonds in solution. This property of the supramolecular organosilane has been exploited to fabricate structuring materials having a superhydrophobic surface property. We have successfully generated the interconnected granular structure with adequate roughness for superhydrophobicity via sol-gel process. Copyright © 2004 American Chemical Society.
