• N-(1-Naphthyl)ethylenediamine dihydrochloride
• Charge-transfer interaction
• Positron annihilation lifetime spectroscopy
• XRD
• Morphology

In this work, structural, thermal, morphological, pharmacological screening and positron annihilation lifetime measurements were performed on the interactions between a N-(1-Naphthyl)ethylenediamine dihydrochloride (NEDA center dot 2HCl) donor and three types of acceptors to characterize these CT complexes. The three types of acceptors include pi-acceptors (quinol and picric acid), sigma-acceptors (iodine) and vacant orbital acceptors (tin(IV) tetrachloride and zinc chloride). The positron annihilation lifetime parameters were found to be dependent on the structure, electronic configuration, the power of acceptors and molecular weight of the CT complexes. The positron annihilation lifetime spectroscopy can be used as a probe for the formation of charge-transfer (CT) complexes.
