Supramolecular synthesis with N-hetero-tolanes: liquid crystals and hydrogen-bonded and halogen-bonded co-crystals
Different co-crystals from N-hetero-tolane derivatives are prepared by hydrogen- or halogen-bonding. Their crystal structures have been determined by single crystal X-ray diffraction (SCXRD). Highly ordered smectic liquid crystals are obtained upon protonation of compound 1 and show a remarkable the...

| Resumo: | Different co-crystals from N-hetero-tolane derivatives are prepared by hydrogen- or halogen-bonding. Their crystal structures have been determined by single crystal X-ray diffraction (SCXRD). Highly ordered smectic liquid crystals are obtained upon protonation of compound 1 and show a remarkable thermal stability. All supramolecular aggregates, crystalline or liquid crystalline, are characterized accordingly by X-ray diffraction (XRD), polarized optical microscopy (POM), and thermal analysis (DSC) |
