Positional and charged effects of heterocyclic N atoms on mesogenic properties of stilbazoles and analogous N-oxides

Article abstract of DOI:10.1080/10587250008031032

The synthesis and the phase behavior of stilbazoles and corresponding N-oxides containing different positions of heterocyclic N atoms, i.e. trans-2′-, 3′-, 4′- stilbazoles and their N-oxides, are reported. Their phase transition temperatures and the mesog
