Abstract

The phenylboronic acids substituted with an azo group on the ortho-position show a significant change in UV-vis spectra upon sugar binding. A new mechanism for the spectral change of the dyes is proposed based on the formation and cleavage of B-N dative bond between boronic acid group and azo group.

摘要

在邻位带有偶氮基团的苯基硼酸在与糖结合时，其紫外-可见光谱会发生显著变化。基于硼酸基团与偶氮基团之间B-N配位键的形成和断裂，提出了染料光谱变化的新机制。
