We report on the synthesis and self-assembly of a new discotic organogelator based on π-conjugated triphenylbenzene with three peripheral chiral substituents. It is found that the introduction of chiral groups to the C3-symmetric molecule led to a hexagonal columnar chiral stacking of the molecules in a clockwise direction in the organogel fibers. And the fluorescent emission of the gel decreased significantly
我们报告了基于具有三个外围手性取代基的π-共轭三苯苯的新型盘状有机胶凝剂的合成和自组装。发现向C 3-对称分子中引入手性基团导致分子在有机凝胶纤维中沿顺时针方向六方柱状手性堆叠。由于在凝胶相中非平面三苯苯核的聚集,与相同浓度的单体状态相比,凝胶的荧光发射显着降低。
