More Information
Summary:A multilayered Langmuir-Blodgett film aggregate, which contains on top of a solid support surface several monomolecular layers of a compound of liquid crystal type preferably having the general formula wherein R' and R'' independently refer to a substantially aliphatic hydrocarbon group of approximately 8 to 30 carbon atoms, Y' and Y'' independently refer to the group -O-, -C(=O)-O-, which over the oxygen atom is bound to the group -(CH2)n- or they refer to -CH2-, n' and n'' independently are zero or 1, R -X-H is a polar group wherein XH refers to hydroxy (OH), carboxyl (COOH), amino (NH2), or an amino group substituted with a substantially aliphatic hydrocarbon group of not more than 30 carbon atoms, and R is a direct bond, a carbonyl group -C(=O)-, lower alkylene or lower alkylene carboxyl lower alkylene, R is hydrogen, lower alkyl or lower alkoxycarbonyl or has the meaning of R -X-H, or the meaning of R'-Y'-(CH2)n'-, provided that the compound (I) does not contain more than three lipophilic groups as defined.
