利用非掌性香蕉形液晶分子自組裝形成具有旋性三級微奈米結構之研究

Hierarchical Superstructures with Helical Sense in the Self-assembly of Achiral Banana-shaped Liquid Crystalline Molecules

指導教授 : 何榮銘 許千樹

摘要


利用非掌性香蕉形液晶分子自組裝形成具有旋性三級結構,說明了三級掌性效應的存在是藉由非掌性香蕉形液晶分子的自組裝造成,而分子規則性會誘導二級分子構形的掌性效應(即彎曲形的化學結構會誘導扭轉的分子構形)因此,彎曲形分子在水溶液中自組裝形成三級螺旋結構是第一個例子說明了非掌性香蕉形分子從分子規則性到三級掌性效應的傳遞過程

並列摘要


Self-assembly of achiral banana-shaped liquid crystalline molecules resulted in hierarchical superstructures with helical sense; suggesting the existence of hierarchical chirality by self-assembling achiral bent-core molecules. Conformational chirality was induced with respect to molecular regularity (i.e., induced twist conformation with bent-core structure). Consequently, the helical superstructure from bent-core molecules with self-assembly in solution is the first example to express the chiral information transfer mechanism of achiral banana-shaped molecules from molecular regularity to hierarchical chirality.
