The present invention relates to a supramolecular polymer comprising quadruple hydrogen bonding units 4H within the polymer backbone, said supramolecular polymer being obtainable by reacting a monomeric unit (a) having the structure 4H* - (Fi)r (IV) and a macromonomeric unit (b) having the structure P-(Fi)s, wherein the monomeric unit (a) is represented by formula (VIIa) or (VIIb), and tautomers and/or enantiomers thereof:
wherein 4H* represents a precursor of the structural element 4H; in formula (IV), Fi represents a reactive group linked to the 4H*-unit; r = 2, so that formula (IV) is represented by F1-4H*-F1 or by F1-4H*-F2; the 4H*-unit is connected to a reactive group (F1) via R1 and to a reactive group (F1) or (F2) via R3, whereas R2 is a random side chain or a hydrogen atom; P represents a polymer chain; in formula (V), Fi represents a complementary reactive group in the macromonomeric unit (b) that is complementary reactive with another Fi of monomeric unit (a); and s = 2 - 6.
本发明涉及一种超分子聚合物,其聚合物骨架中包含四重氢键单元 4H,所述超分子聚合物可通过具有结构 4H* - (Fi)r (IV) 的单体单元 (a) 和具有结构 P-(Fi)s 的大单体单元 (b) 反应获得,其中单体单元 (a) 由式 (VIIa) 或 (VIIb) 表示,以及其同系物和/或对映体:
其中 4H* 代表结构单元 4H 的前体;在式(IV)中,Fi 代表与 4H* 单元相连的反应基团;r = 2,因此式(IV)用 F1-4H*-F1 或 F1-4H*-F2 表示;4H*-unit 通过 R1 与反应基团 (F1) 连接,通过 R3 与反应基团 (F1) 或 (F2) 连接,而 R2 是无规侧链或氢原子;P 代表聚合物链;在式 (V) 中,Fi 代表大单体单元 (b) 中的互补反应基团,该基团与单体单元 (a) 的另一个 Fi 具有互补反应性;以及 s = 2 - 6。
