Abstract

A calix[4]arene derivative containing uracil, 5‐(uracil‐N^1^‐acetamido)‐25,26,27,28‐tetrahy droxycalix[4]‐arene (UC), was designed and synthesized. The interaction with nucleotides and bases has also been studied by ESI‐MS and π‐A isotherms. The results of ESI‐MS showed that UC could recognize adenine and adenosine from other nucleotides and bases. In addition, π‐A isotherms at the air‐water interface indicated that there was interaction between UC and the species in the subphase, and the respective complexes were formed in the monolayer. The mean molecular area at zero surface pressure increased with the sizes of the nucleotides and bases in the subphase in the order: water2.
