Review of Recent Research into Synthesis of Fluorescent Dyes Using Microwave Method

The microwave-assisted has been regarded as a new strategy in the synthesis various organic compounds especially organic dye. The technique offers a lot of advantages as it is simple, rapid, economic and efficient. Dyes are effective molecules have pivotal effects in several fields. Organic dyes were endowed with a diverse of photophysical and photochemical and biomedical applications. Novel microwave synthetic method for many types of dyes including naphthalimides, phenothiazines, fluorescein, pyridinones, cyanines, quinolines, coumarins, triazoloquinoxalines and monoazo disperse dyes were demonstrated. Factors like temperature, type of solvent and power control microwave reactions. Microwaves possess the potential to transport energy from one medium to another in a small duration of 10−9 s with every run of electromagnetic energy. This review highlights microwave applications for the synthesis of dyes with fluorescence, luminescence and photophysical properties.
