James, Tony D. published the artcileNovel saccharide-photoinduced electron transfer sensors based on the interaction of boronic acid and amine, Category: bromides-buliding-blocks, the publication is Journal of the American Chemical Society (1995), 117(35), 8982-7, database is CAplus.
Two boronic acid systems, monoboronic acid 3 and diboronic acid 8, were synthesized. When saccharides form cyclic boronate esters with these boronic acids, the Lewis acid-base interaction between the boronic acid moiety and tertiary amine is strengthened; when saccharides form cyclic boronate esters with boronic acids the acidity of the boronic acid is enhanced. The strength of this acid-base interaction modulates the photoinduced electron transfer (PET) from the amine to anthracene. Both of these compounds show increased fluorescence at pH 7.77 through suppression of the photoinduced electron transfer from nitrogen to anthracene on saccharide binding, a direct result of the stronger boron-nitrogen bond. Compound 3 shows the typical selectivity of monoboronic acids towards saccharides. Compound 8 which has a cleftlike structure is particularly selective and sensitive for glucose due to the formation of an intramol. 1:1 complex between the two boronic acids and the 1,2- and 4,6-hydroxyls of glucose. This is the first example in which ditopic recognition of monosaccharides is achieved in a PET sensor system.
