Abstract

The binding interactions between aqueous copper (Cu2+) and lithium (Li+) ions and Langmuir monolayers and Langmuir− Blodgett (LB) multilayers have been investigated by studying surface pressure− area (Π− A) isotherms and surface potential− area (Δ V− A) behavior in order to find the effective dipole moment, μ⊥, of the calixarene molecules in the uncomplexed and complexed states. The orientation of both calix [4] arenes, namely, 5, 11 ...
