Abstract
Calix[4]resorcinarene (C11TEA) molecules could be deposited as an LB film by the Langmuir–Blodgett (LB) technique onto suitable substrates. Surface plasmon resonance (SPR) and UV–vis spectroscopy were employed for the characterization of these LB films. A high quality and uniform Langmuir monolayer from the water surface can be transferred onto a glass or gold coated substrates with a transfer ratio of over 95%. Thickness and refractive index values of the resultant LB films were measured using surface plasmon resonance with a value of 1.04nm per layer and 1.4 respectively. For the sensing application towards chloroform, this LB film yields a fast and almost fully reversible response to chloroform in few seconds.
