摘要
The role of the structural similarity in the individual components on the self-assembly process of multi-component systems was studied by analysing the gelation properties of chiral multi-component gels with structurally similar (enantiomers) and non-similar donor or acceptor moieties. The gelation properties of the individual enantiomers, mixed enantiomers, and mixed chiral donor-acceptor compounds were analysed in various solvents. Analysis of the mechanical strength revealed that the mixed chiral gels were stronger compared to other gels in mesitylene; however, a reverse trend was observed for thermal stability. Scanning electron microscopy (SEM) of the dried gels of the mixed enantiomeric and mixed chiral donor-acceptor gels showed morphological changes indicating different self-assembly modes. Powder X-ray analysis revealed that a co-assembled mode was observed for the mixed gels with structurally similar components. However, a self-sorting nature was observed for the mixed chiral donor-acceptor gel, and the charge transfer interaction between the donor and acceptor played a major role in the self-assembly of these mixed gels. We performed computational studies to predict the electronic distribution in the individual chiral molecules. These results demonstrate that altering the structural features of the individual components is one of the key parameters that control the self-assembly modes of multi-component systems.
