Liposomal circular dichroism (L-CD) of acyclic amino alcohols exhibit amplification of Cotton effects when measured in highly uniform, unilamellar liposomes. The effect is likely due to intermolecular associations-H-aggregates-that self-assemble spontaneously within the lipid bilayer, and persists over long time scales. L-CD spectra of N,O,O'-tri-(6'methoxy-2'-naphthoyl)-d-erythro-sphingosine, or the
当在高度均匀的单层脂质体中测量时,无环氨基醇的脂质体圆二色性(L-CD)表现出棉花效应的放大。这种效应可能是由于分子间缔合——H-聚集体——在脂质双层内自发地自组装,并持续很长一段时间。N,O,O'-三-(6'甲氧基-2'-萘甲酰基)-d-赤型-鞘氨醇或相应的二氢衍生物(二氢鞘氨醇)的 L-CD 光谱显示,棉花对各向同性溶液中记录的传统 CD 光谱的影响。
