Synthesis and characterization of new polyamide derived from crystal violet dye utilizing as light emitting diode

Abstract EN

New polymer Poly Crystal Violet Terephthalate (PCVT) was synthesis by condensation polymerization of Crystal Violet dye with Terphthalic acid in acidic medium.

The polymer was characterized by several technique such as FT-IR spectroscopy, 1H NMR spectroscopy, X-Ray diffraction (XRD) and Fluorescence technique.

Curing study of new polymer was carried out by Differential Scanning Calorimetric (DSC) under Nitrogen gas, the optimum conditions of curing were obtained like curing temperature, the curing energy and the activation energy of curing (ΔE).

These analysis indicated the correct composition of polymer.

From DSC curve indicate that the reaction type Exothermic, also the Fluorescence spectrum of polymer indicate that there are large change of emission wavelength with high intensity as compare with dye only.

So the new polymer can be used in applications of light emitting diodes.
