| Outline of Final Research Achievements |
A number of luminescent boronic acid-based sensors for sugars, which utilize a reversible reaction between boronic acid and diol, have been exploited so far. However, a fundamental study on how efficiently progresses the sensing reaction is lacking. In this study, we have performed at first equilibrium and kinetic study on the reactions of some boronic acids with diols in aqueous solution in order to get fundamental information for their reactions, which resulted in proposing an universal reaction mechanism of boronic acid with diol. Then, we have performed similar study on the reactions of boronic acid with sugars to identify the reactive species of boronic acid and a sugar in the sensing reaction, and proposed a comprehensive sensing mechanism. Based on the mechanism, we have designed and synthesized highly luminescent metal complexes with boronic acid moiety, and tried to determine a sugar with monitoring the change in luminescence due to its reactions with these complexes.
