  Abstract
  With the aim of significantly improving the applications of charge transfer complexes (CTCs) in the field of electrical and optoelectronic, in the present work we have studied a charge transfer (CT) interaction between organic donor molecules and molecular iodine. In this content, 1,1,4,4-Tetraphenyl-1,3-Butadiene (TPB) and 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) as donor molecules were reacted with I2 to form CTCs. The resulting compounds were characterized by spectral analysis (FT-IR, NMR and UV-Visible spectroscopy). The obtained CTCs have been used to measure band-gap and refractive index values. The observed values indicate possible applicability of tee studied CTCs in the field of optoelectronics.

  Abstract
  This study explores green synthesis as an environmentally friendly and cost-effective method employing selective plant extracts as catalysts for nanoparticle formation. Ananas comosus, a tropical plant rich in essential nutrients and known for its non-toxic, antioxidant, and potentially anticancer properties, was utilized for the synthesis of zinc oxide and nickel-doped zinc oxide nanoparticles. Characterization techniques including UV-Vis Spectrometry, X-Ray Diffraction, and Scanning Electron Microscopy were employed to analyze the optical, structural, and morphological properties of the nanoparticles. Results showed a reduction in the optical band gap of Ni-ZnO compared to pure ZnO, possibly due to absorption of photons by nickel dopant ions in the ZnO lattice. XRD analysis revealed a hexagonal wurtzite structure with predominant diffraction peaks in the (1 0 1) plane, and SEM-EDX confirmed the purity and irregular nanosized shapes (ranging from 21 to 60 nm) of the nanoparticles. Antimicrobial testing using the agar well diffusion method demonstrated promising antimicrobial activity, suggesting potential applications of these nanoparticles as antimicrobial agents in pharmaceutical industries. Overall, this study underscores the feasibility and potential benefits of utilizing Ananas comosus leaf extracts in green synthesis for nanoparticle production with valuable properties for various industrial and medical applications.
