Abstract :
The surface plasmon resonance (SPR) response of metal free phthalocyanine to the exposure NO gases is shown. A shift in resonance leads to the study of the changes of the effective relative permittivity of the overlayer. The SPR response of calix[4]resorcinarene LB films is also shown. Fast and reversible response was obtained by this method. Individual interaction mechanisms were also discussed
