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 kinds of water-soluble methoxy naphthalene-based fluorescent monomers were synthesized from 4-bromo-1,8-naphthalic anhydride. Their excitation and emission spectra were measured. The fluorescence emission spectra predicted by using density functional theory (DFT) and time-dependent density functional (TDDFT) methods are in good agreement with the experimental results.
