influence of a single substituent introduced onto the aromatic core of BTA significantly affects the self-assembly process. The aggregation process of 2-substituted BTAs in the bulk and in solution, as studied by DSC, POM, X-ray diffraction and 1H NMR experiments, is impaired by hydrogen-bond-accepting substituents but strengthened by non-hydrogen-bond-accepting substituents.
N,N',N"-三烷基苯-1,3,5-三甲酰胺 (BTA) 1 或“拥挤”的 BTA 11 和 12 的自组装导致具有有吸引力的材料特性的超分子柱状堆叠结构。据报道,引入三个烷氧基可加强自组装过程。引入到 BTA 芳香核上的单个取代基的影响显着影响自组装过程。通过 DSC、POM、X 射线衍射和 1H NMR 实验研究,2-取代 BTA 在本体和溶液中的聚集过程受到氢键接受取代基的损害,但被非氢键接受取代基加强取代基。
