Synthesis and Characterization of Novel Triphenylene Derivatives Having Carboxylic Acid Groups at the Peripheral Chains

Article Preview

Abstract:

A new kind of triphenylene derivative sym-(OC3H6OCOC2H4COOH)6 with triphenylene at the core and carboxyl groups at the peripheral chains was synthesized and characterized by FT-IR and 1H-NMR. Thermal gravimetry analysis (TGA) and differential scanning calorimetry (DSC) showed that these compounds have a good thermal stability, which is dependent on the flexibility and interaction of the peripheral chains. Red shifts in electronic absorption spectra of the compounds were found in solution with increasing concentration.
