甲氧基萘类荧光单体的合成及其光谱研究

Preparation and Fluorescent Emission Spectra of Methoxy Naphthaline Fluorescent Monomers

以4-溴-1,8-萘二甲酸酐为原料,合成了2种水溶性甲氧基萘类荧光单体,测定了它们的激发光谱和发射光谱。运用密度泛函(DFT)及含时密度泛函(TDDFT)方法预测的荧光发射光谱与实验结果符合得较好。

Two water soluble methoxy naphthaline fluorescent monomers were synthesized by using 4-bromo-1,8- naphthalic anhydride. The fluorescent emission and excitation spectra were investigated. Density functional theory （DFT） and time-dependent density functional theory （TDDFT） were used to calculate the fluorescent emission spectra. The results indicated that the fluorescent emission wavelength were well consistent with the experimental data.
