title = "Synthesis and characterization of 4-phenylethynylphthalic anhydride",
abstract = "4-phenylethynylphthalic anhydride (4-PEPA) was synthesized by the palladium/copper catalyzed Sonogashira coupling reaction between phenylacetylene and 4-bromophthalic anhydride. The yield achieved 85.48\%. The single crystal of 4-PEPA was grown and crystallized by solvent diffusion method. The structure of the compound was characterized by single crystal X-ray diffracttion method, UV-vis, 1H NMR, 13C NMR and FTIR. All characterizations above demonstrated the structure of 4-PEPA. HPLC gave the purity achieving 96.62\%. TG-DSC was used to investigate the thermal stability of the compound. Vibrational frequencies of 4-PEPA calculated using the density functional theory (DFT/B3LYP) method with the 6-31G(d) basis sets were in good agreement with experimental values.",
