一种不饱和荧光单体的制备与性能研究

Study on the preparation of the unsaturated fluorescent monomer and its performances

以2-萘酚-6,8-二磺酸钾和氯丙烯为原料合成了含有不饱和双键的荧光单体2-烯丙氧基萘-6,8-二磺酸钾。对单体反应前后波长变化、荧光强度、耐氯性等进行了测定,试验结果表明:该荧光单体反应后最大发射波长蓝移了90nm,易于监测原料的转化情况,在0～10mg/L范围内,荧光单体的浓度与荧光强度呈很好的线性关系,耐氯性较好,荧光性能稳定。

The fluorescent monomer which has unsaturated double bond, 2-allyloxy naphthalene-6,8-dipotassium disulfonate has been synthesized from 2-naphthol-6,8-dipotassium disulfonate and chloroprope. Based on the de- termination of its performances, such as wavelength, fluorescence intensity and chlorine resistance after the reac- tion, the experimental results show that its maximum emission wavelength changes about 90 nm and it is easy to be inspected and measured. When the concentration of fluorescent monomer is from 0 to 10 mg/L, the relation between concentration and fluorescence intensity is linear. It has good chlorine resistance and excellent fluorescent stability.
