Magnetic orientation of side-chain liquid crystalline polyguanamines

Novel side-chain liquid crystalline polyguanamine with mesogenic groups (LCPGs) exhibited smectic liquid crystallinity. The polymers had an oriented structure under a magnetic field due to higher diamagnetic susceptibility of the mesogenic group. The mesogenic groups could be perpendicularly arranged on a glass substrate under a vertical magnetic field. Furthermore, they were obliquely aligned on the glass substrate by a tilt magnetic field. Tilt angles between the mesogen and the glass substrate were almost consistent with the directions of applied magnetic fields. Magnetic fields afforded various oriented structures, and the magneto-oriented structures were fixed in the samples.
