Paragraph 0039; 0057-0058, (2019/08/30)
The invention relates to a method for synthesizing 8-hydroxyjulolidine. The method comprises the following steps: reacting 3-methoxyaniline, X-(CH2)3-Y and an inorganic base under a heating condition,separating water during the reaction, and carrying out post-treatment after the completion of the reaction to obtain crude 8-hydroxyjulolidine; mixing the crude 8-hydroxyjulolidine with a halogen acid, heating the obtained mixture to react the mixture, and cooling and filtering the obtained solution after the reaction is completed in order to obtain a halogen acid salt of 8-hydroxyjulolidine; andmixing the halogen acid salt of 8-hydroxyjulolidine with water, neutralizing the obtained solution with a base, and carrying out extraction, drying, reduced pressure concentrating, beating and purification to obtain the 8-hydroxyjulolidine. The method has the advantages of abandoning of traditional column chromatography purification, suitableness for industrial production, and high yield.

Three novel iminocoumarin derivatives with high quantum yield are synthesized from 3-benzimidazole substituted coumarin and different aromatic aldehydes. The photophysical behavior of the synthesized compounds was studied using UV-visible and fluorescence spectroscopy in polar and non-polar solvents. The compounds show absorption maxima at around 450 nm and emission maxima at around 500 nm. The quantum yields of compounds in dichloromethane and chloroform are more than 0.90. The absorption, emission and quantum yield of compounds are dependent on the polarity of solvents. Along with an intense absorption, these compounds show shoulder absorption peak in the studied solvents. The solvent polarity plots revealed the charge transfer process in the synthesized molecules from donor to acceptor. Density Functional Theory and Time Dependent Density Functional Theory computations have been used to have more understanding of the structural, molecular, electronic and photophysical parameters of the dyes. The dyes were characterized by FT-IR, 1H NMR, 13C NMR and mass spectral analysis.
