硼酸及其衍生物在熒光分子開關(guān)中的應(yīng)用

熒光分子開關(guān)中主體和客體之間可以通過(guò)多種方式相結(jié)合,其中帶有熒光團(tuán)的硼酸衍生
物與糖或羥基化合物的結(jié)合是通過(guò)共價(jià)鍵形成的。糖化學(xué)在生命科學(xué)中起著非常重要的作用,因此對(duì)糖的識(shí)別和檢測(cè)在醫(yī)學(xué)、細(xì)胞生物學(xué)等領(lǐng)域具有至關(guān)重要的意義。硼酸衍生物可以作為熒光分子開關(guān)對(duì)糖進(jìn)行有效的選擇性識(shí)別,因而受到科學(xué)家們的廣泛關(guān)注。本文對(duì)近年來(lái)國(guó)內(nèi)外相關(guān)研究成果進(jìn)行了綜述。

Abstract 　There are many types of combinations between the hosts and guests in fluorescent molecular switch. Among them , boric acid derivatives with fluorophore may selectively recognize saccharides or hydroxyl compounds through the formation of covalent bond. Since the chemistry of saccharides plays a significant role in life science , the recognition and detection of saccharides are very important in medicine , cellular , biological science and other fields. As a sort of efficient fluroescent molecular sensors , the boric acid derivatives are sensitive and selective in the recogni2 tion of some saccharides and have attracted extensive attentions of many chemists. In this context , the relative results of research about this type of fluroescent molecular switches in recent years were reviewed.
Key words 　Boric acid , Fluorescence , Switch , Sensor , Saccharide
