The Knudsen/Quartz crystal effusion technique was employed for the measurement of vapour pressures as a function of temperature, and derivation of standard molar enthalpies, entropies and Gibbs energies of sublimation, at T = 298.15 K. Static mini-bomb and macro-bomb combustion calorimetry was employed for the determination of standard molar enthalpies of formation in the crystalline phase, at T = 298.15. The great majority of the compounds under study was synthesized by the Suzuki-Miyaura cross-coupling reaction, and characterized by 1H and 13C NMR spectroscopy and by X-ray crystallography. In this work, a series of organic aromatic compounds was studied by various experimental and theoretical methods, with the main objective of obtaining insights about the physical-chemical factors that might lead to structural and energetic differentiation among selected groups of interrelated molecules.
