A series of new phthalimides compounds [3][4][5][6][7] a-i were synthesized from reaction of Malic anhydride, phthalic anhydride, nitro phthalic anhydride, 2-phenyl-4H-benzo [d][1,3]oxazin-4-one, 2-(4-nitrophenyl)-4H-benzo [d][1,3]oxazin-4-one with different amino acids as glycine, alanine, valine, leucine, isoleucine, serine, threonine, tyrosine and Phenyl alanine [1] a-i under fusion conditions. Compounds [3-7] a-i react with SOCl 2 in the presence of benzene to produce compounds [8-12] a-i . Chemical modification of Poly(vinyl alcohol)were obtained by reaction of PVA with compounds [8-12] a-i using the dimethyl formamide to give compounds [13-17] a-i . The structure of the synthesized compounds was characterized by their analytical and spectral data as, IR spectra, 1 H, 13 C-NMR, Elemental analysis (CHN), UV-Vis Spectroscopy, Scanning electron microscopy (SEM), Antibacterial activity were screened via two kinds of bacteria. Also, anticancer activity were examined for most of the modified polyvinyl alcohol.

A new ternary nanocomposite comprising nickel oxide (NiO) embedded into a binary polymeric network of polyaniline (PANI) and polypyrrole (PPy), i.e. PANI‐PPy‐NiO, is synthesized using an in situ chemical oxidative method. The infrared spectrum of PANI‐PPy‐NiO exhibits most of the characteristic peaks of unary nanoparticles with slight shift in the frequencies. The shift is due to the synergistic interaction of binary PANI‐PPy with the inorganic NiO nanoparticles. X‐ray diffraction pattern reveals the semicrystalline structure of the PANI‐PPy‐NiO nanocomposite with an average crystallite size of 22 nm. From Williamson–Hall plot, the micro‐strain value of as‐prepared PANI‐PPy‐NiO is found to be −0.16727. Surface morphology of PANI‐PPy‐NiO shows fine grains of NiO‐encapsulated PANI‐PPy that tend to coalesce and form an agglomeration assembly. The elements detected from energy‐dispersive X‐ray analysis indicate the purity of synthesis of the ternary material. Further, the optical constants obtained from UV–visible spectra (absorption coefficient, extinction coefficient, refractive index, optical conductivity and real and imaginary dielectric constants) are found to be higher for PANI‐PPy‐NiO than for the unary PANI, PPy and NiO nanoparticles. Tauc plot and Urbach energy studies indicate the low bandgap energy of PANI‐PPy‐NiO (2.67 eV) compared to unary nanoparticles. Further, the emission intensity peak (492 nm) observed in the photoluminescence spectrum of PANI‐PPy‐NiO corresponds to the blue region of the visible spectrum. Thus, the optical studies clearly indicate the high suitability of the synthesized PANI‐PPy‐NiO in visible‐light‐based device applications. © 2022 Society of Industrial Chemistry.

PPY, PANI and PPY-PANI-ZnO ternary nanocomposites were synthesized in the laboratory via chemical oxidative polymerization method. The formation of PPY, PANI and corresponding change in the nanostructure with the incorporation of ZnO was examined by X-ray diffraction technique (XRD). Nano-flakes like structure were formed in the PPY-PANI polymeric matrix with the embodiment of ZnO nanoparticles, as examined by surface topology images. Optical transmittance spectra showed the optimized reduced band gap ~2.67eV. Increased rate of electron-hole nonradiative recombination associated to blue and green bands was confirmed from PL spectra. An enhanced current density ~197.75% was examined due to the significantly improved conductivity of PPY-PANI-ZnO ternary nanocomposites. This improved conductivity, reduced band gap and high electron-hole recombination rate confirmed that it can be used as electron transport layer in the OLED devices.
