Periodically birefringent thin films grown out of the isotropic phase of a bent-core banana-shaped liquid crystal

Periodically birefringent thin films growing out of the isotropic phase of the banana-shaped liquid crystal 1,3-pnenylene-bis (4-butoxybenzyldiamine) were investigated with polarized optical microscopy. The gown thin films of the periodic modulation of the birefringent index self-assembled by the banana-shaped LC molecules were attributed to the difference of the molecular composing structures. Further the driving forces of the banana-shaped molecular self-assembly were discussed.
