This paper reports on hybrid organic-inorganic dense membrane materials in which protons and ions are envisioned to diffuse along the hydrophilic pathways. The hierarchical generation of functional hybrid materials was realised in two steps. First, the self-assembling properties of 3-(ureidoarene)propyltriethoxysilane compounds 1-5 in aprotic solvents were determined, revealing the formation of supramolecular

N-(3-silatranylpropyl)-N′-(3-silatranylpropyl)urea (8), respectively. Among these are four novel compounds (5–8), which were characterized by elemental analysis, IR, multinuclear (1H, 13C and 29Si) NMR and mass spectroscopy. Structures of compounds 5 and 6 were deduced by X-ray crystallography. Single crystal X-ray studies revealed distorted trigonal bipyramidal coordination about Si in 5 and 6 with Si–N
本工作旨在合成具有取代的尿素官能团的各种新颖的硅杂环丁烷。将各种胺(吗啉,苯胺,乙二胺和3-氨基丙基三乙氧基硅烷)亲核加成到3-异氰酸根合丙基三乙氧基硅烷中,得到四种三乙氧基硅烷。N- [3-(三乙氧基甲硅烷基)丙基]吗啉-4-羧酸酰胺(1),1- [3-(三乙氧基甲硅烷基)丙基] -3-苯基脲(2),1,2-双 N '-[3 -(三乙氧基甲硅烷基)丙基]脲基}-乙烷(3)和N- [3-(三乙氧基甲硅烷基)丙基] -N'-[3-(三乙氧基甲硅烷基)丙基]脲(4)), 分别。在碱的存在下,所得硅烷与三乙醇胺进行酯交换反应,从而形成相应的硅杂环丁烷,N-(3-硅氧烷基丙基)吗啉-4-羧酸酰胺(5),1-(3-硅氧烷基丙基)-3-苯基脲(6)分别为1,2-双[ N '-(3-硅氨丙基丙基)脲基]-乙烷(7)和N-(3-硅氨丙基丙基)-N'-(3-硅氨丙基丙基)脲(8)。在这些四个新的化合物(5
