This Article addresses the formation of chiral supramolecular structures in the organogels derived from chiral organogelator 1R (or 2R), and its mixtures with its enantiomer (1S) and achiral analogue 3 by extensive circular dichroism (CD) spectroscopic measurements. Morphological analysis by atomic force microscopy (AFM) and scanning electron microscopy (SEM) were complemented by the measurements of their bulk properties by thermal stability and rheological studies. Specific molecular recognition events (1/3 vs 2/3) and solvent effects (isooctane vs dodecane) were found to be critical in the formation of chiral aggregates. Theoretical studies were also carried out to understand the interactions responsible for the formation of the superstructures.
本文通过圆二色性（CD）光谱测量，研究了手性有机凝胶因子 1R（或 2R）及其与对映异构体（1S）和非手性类似物 3 的混合物在有机凝胶中形成手性超分子结构的情况。原子力显微镜（AFM）和扫描电子显微镜（SEM）的形态分析，以及热稳定性和流变学研究的体相性质测量，对其进行了补充。研究发现，特定的分子识别事件（1/3 与 2/3）和溶剂效应（异辛烷与十二烷）对手性聚集物的形成至关重要。还进行了理论研究，以了解形成超结构的相互作用。
