In this work we have been calculated global and local DFT reactivity descriptors for trimethyltetrathiafulvalenylthiophenes (tMeTTF-TP) such as: the ionization potential (I), electron affinity (A), electronegativity (x), electrophicility (ω), and hardness (??) have been calculated using density functional theory (DFT) approach with B3LYP/6-31G(d,p) level of theory. The plots of frontier molecular orbital and molecular electrostatic potential (MEP) have been demonstrated. The chemometric methods PCA and HCA were employed to find the subset of variables that could correctly classify the compounds according to their reactivity.
