Ll. Lai et al., H-bonded complexes of N,N-disubstituted aminophenylazo-(4)-pyridine and benzoic acid derivatives: preparation, mesogenic study and molecular modelling, LIQ CRYST, 28(1), 2001, pp. 157-159
N,N-Disubstituted aminophenylazo-(4)-pyridine forms complexes with a series
of m-alkoxy benzoic acids by intermolecular hydrogen bonding; liquid cryst
alline phases of the resulting complexes are thus induced.
