DFT Investigation of Proton Affinity and Intramolecular Proton–π Interactions in N,N-Dimethylnaphthylamine Derivatives: Insights from Aromaticity, AIM, and NBO Analyses

In this research, the theoretical investigation of intramolecular proton–π (H⁺…π) interactions was conducted on a series of protonated derivatives of N,N-dimethylnaphthalen-1-amine. The primary aim was to examine the characteristics and...
