摘要: Abstract The present paper deals with the use of semi-insulating and conducting LB films as conductimetric sensors. response such sensors consists in conductivity changes induced by gas exposure. Examples collected literature are presented show that technique is very convenient for making continuous ultrathin organic materials exhibiting detection properties towards toxic gases (NO2, PH3,…). Very interesting results have been obtained using mixed even if resulting material mechanism not well understood. Some multifunctional required conduction transduction ‘recognition properties’ selective detection. With goal, associated chemistry provides undeniable advantages.
