| Outline of Final Research Achievements |
In this study, our ongoing program to explore functionalization of chiral nano-architectures led us to apply mono-dispersed boronate particles, obtained by boronic acid-based hierarchical self-assembly, to support materials for the use as asymmetric heterogeneous catalysts. Preparation of chiral tartaric acid-bound boronate ensembles with aggregation-induced emission (AIE) capability was also conducted. In the former case, boronic acid-appended N-formyl-L-valine derivative was newly synthesized and grafted boronate microparticles. The resultant hybrid systems served as asymmetric heterogenious catalysts for the reductive reaction of ketimines in the presence of trichlorosilane. On another front, AIE-active boronate tartaric acids showed an enantioselective emission for chiral diamines and natural cinchona alkaloids.
