Chirally-oriented lipid aggregates were doped into a solid polymer film, which was readily prepared by casting and removing a solvent from anionic l-glutamide-derived organogels and polystyrene. When a cationic achiral dye was mixed into this system, the resultant polymer film showed tunable circular dichroism (CD) due to chiral complex formation with the achiral dye on the highly-ordered structures
将手性取向的脂质聚集体掺入固体聚合物膜中,该固体膜可通过从衍生自阴离子型l-谷氨酰胺的有机凝胶和聚苯乙烯中流延并除去溶剂而容易地制备。当将阳离子非手性染料混合到该体系中时,由于在基于1-谷氨酰胺脂质的高度有序结构上与非手性染料形成手性络合物,所得的聚合物膜显示出可调谐的圆二色性(CD)。
