摘要:
Many nematic liquid crystals are not able to form stable monolayers at the air/water interface because of the lack of a polar headgroup. A possible way to obtain a monomolecular film with these compounds is to incorporate them into host monolayers of amphiphilic compounds. Stable monolayers containing a high fraction of the liquid crystal can be obtained. We have prepared stable and transferable monolayers of MBBA (which is not an amphiphilic compound) using octadecylmalonic acid (OMA) as host. The monolayers at the air/water interface have been characterized by measurements of surface-pressure/area and surface-potential/area isotherms. The monolayers deposited on quartz plates have been characterized by determining the transfer ratio and by spectroscopic measurements.
