Poly-(gamma -benzyl-L-glutamate) molecules have been bonded covalently to a flat substrate via carbonyl end group to form an aligned dipole layer (CRA film). The authors have evaluated the electric influence of the CRA film on the dynamic change of the hydrogen-bonded liquid crystalline complex of 4-hexyloxybenzoic acid and 4-nonylpyridine (60BA-9Py) by means of time-resolved infrared spectroscopy. Using the CRA film as an orienting film for 60BA-9Py, the absorbance change of the complex when burst electric field was applied had many steps in response to the change of its sign. Moreover, the movement of the 60BA-9Py complex was induced by an external electric field, not only in the direction of the complex long axis but also in that of the complex short axis. This characteristic dynamic behavior of the 60BA-9Py complex was due to the weak hydrogen bonding.
