含羧基噻唑橙荧光染料的合成、修饰与光谱特性

Synthesis, Modification and Fluorescence Characteristic of the Thiazole Orange Fluorescent Dye with Carboxyl

合成了含有羧基的噻唑橙(TO-COOH),同时采用壳聚糖(CTS)对其进行修饰,得到噻唑橙-壳聚糖(TO-COOH-CTS),并通过红外光谱(IR)、差示扫描量热法(DSC)等测试手段对TO-COOH-CTS结构进行表征.研究了该染料的荧光特性,壳聚糖修饰的TO-COOH具有明显的荧光增强效应.

In this paper, the Thiazole Orange （ TO ）with carboxyl （namely TO-COOH） was synthesized and modified by chitosan oligosaccharide （CTS）to produce Thiazole Orange-chitosan oligosaccharide（TO-COOH-CTS）. The target compound was confmned by infrared spectrum（IR） and differential scanning calorimetry（DSC）test mode.The effect of the fluorescence enhancement on TO-COOH-CTS was shown obviously by the fluorescence spectrum.
