Using solution and solid-state analyses, we demonstrate that the tripodal N-methylated(1,3,5-benzene-tricarboxamide)-tris(phenylurea) BTA ligands, possessing urea functionalities in the meta position, are able to form extended self-assembly 2D networks via hydrogen bonding templated by sulfate (SO42–). The divergence of the urea binding sites confers a propeller-like conformation to the ligands and
使用溶液和固态分析,我们证明三脚架N-甲基化(1,3,5-苯三甲酰胺)-三(苯基脲)BTA配体在间位具有尿素官能团,能够形成扩展的自-通过以硫酸盐为模板的氢键(SO 4 2–)。尿素结合位点的差异赋予配体螺旋桨状构象,并且是形成自组装体的关键。在溶液和固态中的研究以及对配体自组装性质的扫描电子显微镜(SEM)研究表明,这种会聚作用还导致形成分层结构,包括多孔膜和球形纳米尺寸的颗粒。形态学结果高度依赖溶剂。
