A library of dimeric and trimeric phthalonitriles linked by a single aromatic ring: comparative structural and DFT investigations

Abstract

A library of five phthalonitriles, dimeric or trimeric, all connected by an aromatic spacer (catechol, resorcinol, hydroquinone, phloroglucinol and catechol with two tert-butyl moieties), was selected to be comparatively studied from a structural point of view. Hirshfeld surface analysis and DFT calculations were performed as well.
