摘要:

氢键具有方向性,是管状、线状和网格状等立体结构聚合物形成的常见形式。 本文以1,3-交替-25,26,27,28-四正丙烷基杯[4]芳烃为原料,连接噻吩环加深空穴并增强其刚性结构,交替的两组手臂末端修饰不同基团(包括: —COOH、—CONH2和—COOCH3),形成1,3-交替杯[4]芳烃结构单元。 其中,1,3-交替杯[4]芳烃羧酸和酰胺衍生物会通过氢键聚合,扫描电子显微镜(SEM)观察到它们能形成一维管线状聚合物,并考察了位阻、溶剂环境及浓度对氢键聚合的影响。 聚合物形成后会影响其发光性能和热稳定性: 羧酸和酰胺衍生物溶液的红外光谱有明显的氢键聚合现象; 它们的固体荧光比酯衍生物明显红移(>25 nm)且量子产率高(>20%); 热稳定性好,高达370 ℃,比酯衍生物高约35 ℃。 本研究工作为1,3-交替杯[4]芳烃聚合物在光热材料的应用奠定了基础。

Abstract:

Hydrogen bonds have directionality and are a common form of supramolecular assembly in tubular, linear, and network-like three-dimensional structures. In the study, 1,3-alternating-25,26,27,28-tetrapropyl cup[4]arene was used as the starting material, with aromatic thiophene rings incorporated to deepen its cavity and enhance its rigid structure. The two alternating arms were modified with different functional groups (including —COOH, —CONH?, and —COOCH?), forming typical 1,3-alternate calix[4]arene supramolecular structural units. The carboxylic acid and amide derivatives of 1,3-alternate [4]arene underwent hydrogen bonding polymerization, which, as observed by scanning electron microscopy (SEM), led to the formation of one-dimensional tubular polymers. The effects of steric hindrance, solvent environment, and concentration on hydrogen bond polymerization were investigated. Once the polymers were formed, they affected their luminescent properties and thermal stability: Infrared spectra of them in solutions showed significant hydrogen bonding polymerization; Their solid-state fluorescence exhibited a marked red shift (>25 nm) compared to ester derivatives, with a high quantum yield (>20%); And they demonstrated good thermal stability, over 370 ℃, about 35 ℃ higher than that of ester derivatives. This study laid the foundation for the application of 1,3-alternate [4]arene polymers in photothermal materials.
