摘要
Azopyridine-containing hexacatenar silver complexes have been synthesized and their liquid crystalline and photoisomerization behaviours investigated. These silver complexes (1a - d) exhibit hexagonal columnar liquid crystalline phases, whose structures were confirmed using polarizing optical microscopy and small angle X-ray diffraction.
