Synthesis, Thermal, and Light-Emitting Properties of Anthracene Derivatives

Abstract

Several anthracene derivatives were prepared by a single-step reaction and characterized their thermal properties by differential scanning calorimetry (DSC) and thermogravimetric analyses. Their photoluminescence properties were examined in a large number of organic solvents of increased polarity that included toluene, chloroform, tetrahydrofuran, acetone, methanol, acetonitrile, and dimethyl sulfoxide. Some compounds exhibited emission spectra with vibrational fine structures in organic solvents; and other compounds exhibited structureless emission spectra in organic solvents.

Keywords:

• anthracene derivatives
• differential scanning calorimetry
• photoluminescence
• vibrational fine structures
