Fabrication of controlled supramolecular assembly and establishing the structure-function relationship was of great significance in supramolecular chemistry. Uniform fluorescence supramolecular polymeric vesicles and/or micelles with enhanced photophysical property were elaborately designed and prepared by amphiphilic block polymer hosts bearing pillar[5]arene units, which following the working mechanism of synergistically confined effect of hydrophobic interactions and host-guest interactions. Additionally, transformation from supramolecular polymeric vesicles to supramolecular polymeric micelles was achieved by selecting different length of hydrophilic segments in block polymer hosts. The optical performance was detailed deciphered by the impact factors including guest patterns, density of pillar[5]arene unit, length of hydrophilic segments and solvent environment. By exploiting amphiphilic block polymer hosts, efficient artificial light-harvesting systems with ordered arrangement of donor and acceptor molecules were well constructed to realize tunable emission wavelength, which was used as Morse code for information encryption matrix with high storage capacity capable of simultaneously storing Chinese, English and digits.

基于两亲性嵌段聚合物宿主的组装控制超分子聚集诱导发射系统


制备受控超分子组装体和建立结构-功能关系在超分子化学中具有重要意义。采用两亲性嵌段聚合物主体精心设计，制备了具有增强光物理性能的均匀荧光超分子聚合物囊泡和/或胶束，其工作原理遵循疏水相互作用和主客体相互作用的协同限制效应。此外，通过在嵌段聚合物宿主中选择不同长度的亲水链段，实现了从超分子聚合物囊泡到超分子聚合物胶束的转变。通过影响因素（包括客体模式、柱[5]芳烃单元密度、亲水链段长度和溶剂环境）详细解读了光学性能。通过利用两亲性嵌段聚合物宿主，很好地构建了高效的人工光捕获系统，使供体和受体分子有序排列，实现了可调谐的发射波长，并被用作信息加密矩阵的莫尔斯电码，具有高存储容量，能够同时存储中文、英文和数字。
