| Research Abstract |
Sandwich cell was prepared with a glass substrate which coated with monolayer having linear alkyl tail. When 4-cyano-4'-n-pentyl-biphenyl (5CB) was penetrated into this cell, LC phase was observed by polarized microscope. The observed texture was similar to those for the monolayer on the surface of the water. When the length of alkyl tail was 16 or 18, the induced orientation of 5CB was observed even if the chain density was 5.0 chain/nm2. On the other hand, it was revealed that the induced orientation was restricted when the number of carbon was 20. Orientation control does not motivated through interdigitation of LC tail and the alkyl chain of the adsorption films. In addition, I showed that the fluidity (mobility) of the alkyl chain which came in contact with a liquid crystalline aspect in liquid crystalline temperature (22.5-35 degrees Celsius) of 5CB was important when this instruction orientation occurred.
