Abstract

Self-assembled monolayers containing cavitand recognition sites have been used for the first time as an interface for vapor detection using surface plasmon resonance (SPR). Fast response times (t90% < 1 s) and high sensitivity for tetrachloroethylene over other chlorinated hydrocarbons were measured with a monolayer of the resorcin[4]arene cavitand adsorbate shown in the Figure.
