dc.description.abstract |
Within this article, we report the characterization and organic vapor sensing
properties of Langmuir-Blodgett (LB) thin films of calix[8]arenes. Surface
pressure-area isotherms show that very stable monolayers are formed at the air-
water interface. The LB film could be deposited onto different substrates which
allowed the films to be characterized by UV, quartz crystal microbalance (QCM),
surface plasmon resonance (SPR) and atomic force microscopy (AFM). The results
indicate that good quality, uniform LB films can be prepared with transfer
ratios of over 0.95. QCM results showed that the deposited mass of calix[8]arene
monolayer onto a quartz crystal decreased from 693 to 204 ng as the number of
layers is increased. AFM studies showed a smooth, and void free surface
morphology with a rms value of 1.202 nm. The sensing abilities of this LB film
towards the development of room temperature organic vapor sensing devices are
also studied. Responses of the LB films to various vapors are fast, large, and
reversible. It was found that the obtained LB film is significantly more
sensitive to chloroform than other vapors. It can be concluded that this
molecule could have a potential application in the research area of room
temperature vapor sensing devices. (C) 2010 Elsevier B.V. All rights reserved. |
