1,3-交替杯[4]芳烃衍生物的制备及其氢键聚合
Preparation of 1,3-Alternate Calix[4]arene Derivatives and Their Hydrogen-Bonding Polymerization
摘要
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,—CONH2,and—COOCH3),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.关键词
