Abstract

Understanding the origin of physical-chemical properties of molecules is crucial for the development of new materials. However, due to the limitations of conventional experimental techniques, this is not an easy goal to achieve. The accuracy required to overcome this challenge is available through isolated-phase studies. In this case, the intrinsic properties of a new family of a high conductance foldamer based on anthracene monomers have been studied by means of RIDIRS (Resonant Ion Dip Infrared Spectroscopy) laser spectroscopy and supersonic expansion. The comparation between the inherent infrared experimental spectrum of the isolated molecules and DFT (Density-functional theory) calculations has determined the predominance of the π-π interactions between anthracene monomers, which underlines the effectiveness of laser spectroscopy as a great complement to other characterisation techniques.
