IRRAS studies on chain orientation in the monolayers of amino acid amphiphiles at the air-water interface depending on metal complex and hydrogen bond formation with the headgroups
Article Abstract:
A study on the monolayers of N-octadecanoyl-L-alanine at the air-water interface on pure water and metal ion containing subphases is carried out by using polarized infrared reflection-absorption spectroscopy (IRRAS). The findings show that the chain conformation and tilt are closely related to the formation of intramolecular hydrogen bonds and the ionic interaction of the metal complex in the cases of Ca(super 2+) and Cu(super 2+).

Molecular recognition of cytosine- and guanine-functionalized nucleophiles in the mixed monolayers at the air-water interface and Langmuir-Blodgett films
Article Abstract:
Molecular recognition of mixed nucleolipids of 1-(2-octadecyloxycarbonylethyl)cytosine and 7-(2-octadecyloxycarbonyethyl)guanine in the monolayers at the air-water interface and Langmuir-Blodgett (LB) films is investigated. A very different base orientation and intermolecular interaction in the mixed monolayers are presented in comparison to those in the monolayers on the complementary base-containing subphase.

Roles of metal complex and hydrogen bond in molecular structures and phase behaviors of metal N-octadecanoyl-L-alaninate Langmuir-Blodgett films
Article Abstract:
The N-octadecanoyl-L-alanine Langmuir-Blodgett (LB) films deposited from aqueous subphases containing metal ions at their intrinsic pH values are examined by FTIR spectroscopy. The results indicate that hydrogen bond and metal complex play an important role in the molecular structures and phase behaviors of the metal complex LB films.
