In this context the already extensive work of Rein-houdt and coworkers on the preparation and characterization of self-assembled monolayers of resorcin [4] arenes [11-13], calixarenes [14], and even carceplexes [15] constitutes one of the most important efforts to develop this field. Self-assembled monolayers of resorcin [4] arenes exhibit selective adsorption properties for small chlorinated hydrocarbons in the gas phase [13], although serious questions have been raised as to how much the observed selectivity has to do with the presence of molecular cavities in the monolayer assembly [16]. Davis and Stirling have also reported on the self-assembly of similar compounds and demonstrated the formation of multilayers [17,18]. The extensive and very systematic work of Crooks, Ricco and co workers on the development of devices for the detection of volatile organic compounds deserves special mention [19]. Recently, Crooks and coworkers have taken a very interesting turn in their work, demonstrating that monolayer-attached dendrimeric structures exhibit remarkable selectivity for the sorption of gas-phase molecules [20,21].
