The fluorescence sensor for saccharide based on internal conversion.

Sun XY1, Liu B.

Luminescence. 2005 Jul-Oct;20(4-5):331-3.

In this paper, an internal conversion (IC) fluorescence probe N-(o-boronic acid)benzyl-1-naphthylamine (BBNA) was prepared from 1-naphthylamine and 2-formylbenzeneboronic acid. The fluorescence parameters of BBNA were investigated in a variety of solvents. When BBNA interacted with D-fructose in phosphate buffer solution of 30% MeOH, pH 8.21 (v/v), the fluorescence intensity increased and emission maximum red-shifted slightly with increasing D-fructose concentration. In the presence of D-fructose, the fluorescence quantum yield of BBNA increased with increasing solvent polarity, suggesting that internal conversion (IC) occurred with BBNA. The binding force of BBNA with d-fructose was the strongest, and the stability constant (K) of D-fructose was 99.9 mol/L. Therefore, a selective recognition system based on IC was constructed for D-fructose.Copyright 2005 John Wiley & Sons, Ltd.
