光敏型多酸杂化分子及其光响应特性是目前多酸功能材料的研究重点.本文采用共价修饰的方法将光敏型查耳酮基团嫁接至Anderson型多酸骨架上,制备了一类新型的光敏杂化分子.利用核磁共振、傅里叶转换红外、高分辨质谱、单晶X射线衍射等技术确认了多酸-查耳酮分子的结构;并利用紫外光谱、核磁共振和凝胶渗透色谱技术详细研究了多酸-查耳酮分子的光交联特性.该工作为新型光敏多酸杂化分子的制备及功能应用提供了良好借鉴.
Photosensitive polyacid hybrids and their photoresponsive properties are currently the focus of polyacid functional materials.In this paper, photosensitive chalcones were grafted onto the Anderson polyacid skeleton by covalent modification, A new type of photosensitive hybrid molecule has been synthesized and characterized by means of NMR, FT-IR, high resolution mass spectrometry and single crystal X-ray diffraction. The structure of polyacid-chalcone molecule has been confirmed by UV spectroscopy, nuclear magnetic resonance and gel The results of permeation chromatography showed that the photocrosslinking of polyacid-chalcone molecule was studied in detail.The work provided a good reference for the preparation and functional application of the novel photosensitive polyacid hybrids.
