间苯二酚型杯芳烃诱导叶红素和叶黄素组装的多

本期文章:《美国化学会志》:Online/在线发表

一个由扬州大学孙燕课题组带头的合作小组在超分子化学领域取得一项新突破,他们通过间苯二酚型杯芳烃诱导叶红素和叶黄素组成多层级超分子结构,相关论文于2020年11月23日发表在《美国化学会志》上。

在该文章中,研究人员报道了由水溶性的胺修饰的间苯二酚型杯芳烃和β-叶红素形成的管状超分子结构,而用叶黄素替换叶红素则会形成微层状超分子结构。研究人员通过多种手段表征了这些结构,并发现了间苯二酚型杯芳烃与叶红素/叶黄素结合位点的差异。另外,研究人员还通过计算这些结构组装时的能量变化进一步描述了其组装机理。

据了解,操控叶红素组成的多层级超结构有一些引人注目的特性,使其有望在光合作用和生物研究中获得应用。

Abstract: The manipulation of carotenoid-based hierarchical superstructures affords attractive properties that facilitate application in biology and photosynthesis. Here, tubular suprastructures formed from water-soluble amide-modified resorcinarene and β-carotene were reported, whereas microsheets were formed when β-carotene was replaced with lutein. These structures were characterized using various measurements, indicating the differences of binding sites between resorcinarene and β-carotene/lutein. Subsequently, the assembly mechanism was described by calculating the formation energy of the assemblies.
