Abstract

Molecular-structured systems have been received a lot of attention due to improved processability and performance for several technology areas. For these aim there are great investments in methodologies that lead to a structural control both at the dimensional and morphological levels, seeking to obtain materials with specific properties and functions. In this context, for the development of new materials, periodic gels and solids based on organic molecules are good candidates to improve the performance of devices. The proposal aims at a thorough investigation on polysilsesquioxane and supramolecular gels and organic crystals. Among the gains the use of high resolution microscopic techniques for the identification of the nano and micrometric arrangement of the sol/gel phase, diffraction and scattering X-ray techniques and others for the characterization of these materials. Also, we will start an inedited investigation about ordered-materials induced by anion-p supramolecular interactions. These scientific topics have been developed in the current project, FAPESP 2017/13839-0, and the collaboration with the group of Supramolecular Chemistry, coordinated by Prof. Jonathan W. Steed - Durham University - could provide a great improvement to the research work. (AU)
