Copper(II) ion induced monolayer formation of p-tert-butylthiacalix[4]arene at the air–water interface - ScienceDirect
摘要:
The monolayer properties of p- tert-butylthiacalix[4]arene (TCA) at the air–water interface was investigated by the measurements of surface pressure–area isotherms. However, TCA only exists as a trimmer aggregate on the subphase of deionized water. Copper(II) ion in the subphase can induce the monolayer formation of TCA. The UV-Vis spectra and FTIR spectra of the transferred films suggested that the monolayer formation was fulfilled through the coordination of copper(II) ion to TCA at the air–water surface.
