Abstract
Abstract Three new 9-arylanthracene-based π-conjugated derivatives with different side substituent (methyl, methoxy, and hexyloxy) were synthesized using Heck coupling/Horner–Emmons reaction in good yields (72–78%) and their photophysical properties investigated. The dependence of the photophysical properties on the side substituent methyl, methoxy, and hexyloxy has been discussed. The absorption maxima of the synthesized compounds in the solution possess similar absorption bands located at 420–423 nm. They are shown to be thermally stable and emit light in sky blue region (ca. 490 nm) in solution. Photoluminescence measurements show a 25–28 nm red shift between solution and powdered states indicated some aggregation in the solid state. The results of cyclic voltammetry measurements of the compounds show good reversibility, indicating that the compounds have good electrochemical stability.
