Abstract
This paper presents the detection performances of low-conducting Langm uir-Blodgett (LB) films, based on tetracyanoquinodimethane (TCNQ) and tetrothiafulvalene (TTF) derivatives, towards nitrogen dioxide (NO2). TTF-based LB films appear to be more sensitive than TCNQ ones, and wel l adapted to the detection of low concentrations. The detection mechan ism is clearly established for TCNQ LB films, but is still unclear for LB films based on TTF.
