ABSTRACT
In order to significantly enhance the applications of charge transfer complexes (CTCs) in electrical and optoelectronic fields, we have investigated the charge transfer (CT) interaction between organic donor molecules and molecular chloranil. Specifically, 1,1,4,4-Tetraphenyl-1,3-Butadiene (TPB) and 2,2,6,6-Tetramethylpiperidine-N-oxyl (TEMPO) were utilized as donor molecules and reacted with chloranil to form CTCs. The resulting compounds were analyzed using spectral techniques such as FT-IR, NMR and UV-Visible spectroscopy. These methods provided detailed insights into the structural and electronic properties of the CTCs. The CTCs obtained from these reactions were employed to measure band-gap and refractive index values, key parameters in determining the suitability of materials for optoelectronic devices. The observed values indicate that the studied CTCs exhibit promising characteristics for potential applications in optoelectronic technologies, such as in the development of advanced sensors, photovoltaic cells, and light-emitting diodes.
