Preparation and characterization of calix[6]arene Langmuir–Blodgett thin film

Abstract

Calix[6] arene monolayer/multilayer was prepared on a glass substrate and the behavior of monolayer properties investigated at the air-water interface by taking Langmuir isotherm graph. UV-visible, wettability measurements, atomic force microscopy and quartz crystal microbalance measurements were used to monitor the deposition quality of this Langmuir-Blodgett film. Our results showed that a uniform and high quality film with a transfer ratio of approximately 0.99 occurred using the calix[6] arene material at a deposition pressure of 21 mN/m. The surface free energy was determined to be 25.86 mN/m based on contact angle measurements.
