A widespread application and nonbiodegradability of the poly(ethylene terephthalate) (PET) have created a huge amount of waste, which is imposing a serious life-threatening environmental problem. In this study, we have utilized the PET waste to synthesize disodium terephthalate (DST), an organic salt having two Na + ions per molecule. The purity of the DST phase was confirmed by Fourier transform infrared spectroscopy, X-ray diffractometry (XRD), and thermogravimetric analysis (TGA). A new poly(ethylene oxide)-DST polymer electrolyte was synthesized for utilizing Na + ions of the DST. The electrical conductivity of the electrolyte was optimized by varying the [O]/[Na + ] mole ratio with temperature and the results were explained using the XRD and differential scanning calorimetry studies. The TGA study showed that the electrolyte is thermally stable up to 200 C.

Lanthanide-Based Coordination Polymers with a 4,5-Dichlorophthalate Ligand Exhibiting Highly Tunable Luminescence: Toward Luminescent Bar Codes

Reactions in water of 4,5-dichlorophthalate (dcpa) with the heaviest lanthanide ions lead to a family of compounds with the general chemical formula [Ln(dcpa)(HO)·3HO], where Ln = Tb-Lu, Y. The synthesis, crystal structure, thermal behavior, and luminescent properties of this series of homonuclear compounds are described. Additionally, this family can be extended to isostructural heteronuclear compounds that can contain some light lanthanide ions and therefore present some original photophysical properties. These compounds show potential interest as multiemissive materials (visible and infrared light between 450 and 1600 nm) and could find application as luminescent bar codes.

“…In the present case, the phenyl ring is a regular hexagon with bond lengths somewhere in between the normal values for a single (1.54 Å) and a double (1.33 Å) bond. [68] Analysis of organic molecules having conjugated π-electron systems and large hyperpolarizability using infrared and Raman spectroscopy has evolved as a subject of research. [69] The potential application of the title compound in the field of nonlinear optics demands the investigation of its structural and bonding features contributing to the hyperpolarizability enhancement, by analyzing the vibrational modes using IR and Raman spectroscopy.…”

The Fourier-transform infrared and Fourier-tranform Raman spectra of phenyl phosphate disodium salt were recorded and analyzed. The surface-enhanced Raman scattering (SERS) spectrum was recorded in a silver colloid. The vibrational wavenumbers of the compound were computed using the Hartree-Fock/6-31G * basis and compared with the experimental values. The molecule is adsorbed on the silver surface with the benzene ring in a tilted orientation. The presence of the phenyl ring and the phosphate group vibrations in the SERS spectrum reveal the interactions between the phenyl ring and the phosphate group with the silver surface. The first hyperpolarizability is calculated, and the calculated molecular geometry is compared with those of similar reported structures.
