The mechanofluorochromism is related to the optical properties according electron push–pull substituent effect. As intramolecular charge transfer decreases, strong intermolecular interactions occur, leading mechanofluorochromism.

Control of intermolecular interactions is integral to harnessing self-assembly in nature. Here we demonstrate that control of the competition between hydrogen bonds and halogen bonds, the two most highly studied directional intermolecular interactions, can be exerted by choice of solvent (polarity) to direct the self-assembly of co-crystals. Competitive co-crystal formation has been investigate...

In the present work, an in-depth, qualitative and quantitative description of non-covalent interactions in the hydrogen storage materials LiN(CH3)2BH3 and KN(CH3)2BH3 was performed by means of the charge and energy decomposition method (ETS-NOCV) as well as the Interacting Quantum Atoms (IQA) approach. It was determined that both crystals are stabilized by electrostatically dominated intraand i...

Due to the unpredictable nature of organic fluorine in its participation in the formation of different supramolecular motifs which concomitantly influences the physicochemical properties of the compounds of interest, the study of noncovalent interactions involving organic fluorine will always be an expanding area of research amongst the scientific community. The participation of organic fluorin...
