Abstract : Universiti Pendidikan Sultan Idris
In this work, the characterization of calix [4] arene (C4) and calix [8] arene (C8) were studied using LangmuirBlodgett (LB) technique, surface potential meter and UV-Visible spectrometer. The surface pressure - area isotherms demonstrated stable Langmuir C4 and C8 monolayers formed at the air/water interface. Several properties such as limiting area per molecule and molecule radius of C4 and C8 were determined using different spreading volumes in LB technique. Besides that, effective dipole moments and maximum surface potential of C4 and C8 were determined from surface potential values. In addition, UV-Vis spectroscopy stated that the peak absorbance of C4 occurred at 275nm with one “shoulder” peak exists at 283nm, whilst peak absorbance of C8 occurred at 287nm. Surface topography for C4 and C8 thin layer also been observed. This study wasper formed to determine several basic properties of these calixarenes for future works.
