Outline of Final Research Achievements

Sequential dehydration of diboronic acids with polyhydric alcohols gave mono-dispersed boronate fine particles. In this study, our interest for functionalization of the surface led us to deposit nano-metals (Au, Pd, Ru, etc) by deposition reduction method in the presence of polyethyleneimine. The resultant hybrids show efficient catalytic activities for fine chemical reactions. Furthermore, such a reactive surface of boronate fine particles motivated us to graft dyes on the surface, allowing the development white light emissive particles. For this approach, the introduction of cation binding site into the dye grafted endowed the particles with chemosensing capabilities for metal ions. In addition, the use of aggregation-induced emission (AIE)-active units for the particle formation was found to be profitable for the functionalization.
