Abstract

Abstract: Long-chain derivatives of Kemp's acid formed stable monolayers at the air-water interface, where the carboxylic acid groups produced the cyclic dimer species and served as a molecular cleft for specific binding of nitrogen aromatics and amino acids. The structure of the long-chain substituents was crucial for forming the cyclic dimer. Combinations of FT-IR, XPS, and UV spectroscopies of LB films and surface pressurearea isotherms revealed that ...
