摘要：
Achiral supramolecular hydrogen bonded complexes between rodlike 4-(4-alkoxyphenylazo) pyridines and a taper shaped 4-substituted benzoic acid form achiral (Ia % 3d) and chiral "Im% 3m-type" bicontinuous cubic (I432) phases and a chiral isotropic liquid mesophase (Iso(1)([)*(])). The chiral phases, resulting from spontaneous mirror symmetry breaking, represent conglomerates of macroscopic chiral domains eventually leading to uniform chirality.
