摘要：

This paper presents the detection performances of low-conducting Langmuir-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 well adapted to the detection of low concentrations. The detection mechanism is clearly established for TCNQ LB films, but is still unclear for LB films based on TTF.
