A polygonal scaffold includes at least three polyproline II (PPII) helix rods and at least three connectors. Each of the PPII helix rods is composed of a plurality of repeat units represented by Formula (i), and at least one of the PPII helix rods has at least one hydrogen atom of at least one of the repeat units being substituted by a first chemical handle for connecting a ligand. Each of the connectors is a divalent organic group, and every two of the PPII helix rods are connected by one of the connectors to form a closed ring. Therefore, with the uniform composition, the PPII helix rods have a stable helical structure under aqueous conditions, and a desired rigidity can be provided.
多边形支架包括至少三个聚脯
氨酸 II(P
PII)螺旋杆和至少三个连接体。每根 P
PII 螺旋杆都由式(i)表示的多个重复单元组成,并且至少有一根 P
PII 螺旋杆的至少一个重复单元的至少一个氢原子被用于连接
配体的第一
化学柄取代。每个连接体都是二价有机基团,每两个 P
PII 螺旋杆由一个连接体连接,形成一个闭环。因此,在组成均匀的情况下,P
PII 螺旋杆在
水性条件下具有稳定的螺旋结构,并能提供所需的刚性。
