Abstract：

Multilayer　molecular　films　of　polyelectrolyte/calixarene　and　polyelectrolyte/cyclodextrin　hosts　were　fabricated　by　alternating　adsorption　of　charged　species　in　aqueous　solutions　onto　a　substrate　(quartz　or　silicon　wafer).　This　layer-by-layer　molecular　deposition　approach　has　been　successfully　used　to　integrate　molecular　recognition　reagents　into　polymer　films　as　chemically　selective　layers　for　surface　acoustic　wave　(SAW)　chemical　sensing　applications.　The　resulting　sensors　have　high　sensitivity　and　selectivity　to　the　organic　vapors　studied.　The　films　were　characterized　with　SEM,　infrared　and　UV-vis　spectroscopy,　and　monitored　by　SAW　devices.　These　measurements　revealed　that　the　deposition　process　is　highly　reproducible　and　the　resulting　films　are　uniform　and　stable.　©　1997　Elsevier　Science　S.A.
