“…In some cases, electron transfer occurs on the component mixed in conducting polymers. Phthalocyanines are good π-electron donors, so when a composite film of phthalocyanine (Pc) and conducting polymer exposed to NO 2 , electrons will transfer from Pc to NO 2 , leading to a increase in charge carriers (hole) [ 22 , 52 , 53 ]. In other work, Fe 2 O 3 was found to be the chief active material in Fe 2 O 3 /PPy composite film [ 54 ].…”

The gas sensors fabricated by using conducting polymers such as polyaniline (PAni), polypyrrole (PPy) and poly (3,4-ethylenedioxythiophene) (PEDOT) as the active layers have been reviewed. This review discusses the sensing mechanism and configurations of the sensors. The factors that affect the performances of the gas sensors are also addressed. The disadvantages of the sensors and a brief prospect in this research field are discussed at the end of the review.

Proton Translocation in Monomolecular Langmuir−Blodgett Films Including 2-Naphthol and 1,4-Anthraquinone Derivatives

et al. 2005

The scope of the present work is the investigation of proton transport through monomolecular Langmuir-Blodgett (LB) films. The films were formed from amphiphilic molecules: 2-naphtholo-6-sulfonamide of dodecylamine (N) and 1,4-anthraquinono-2 sulfonamide of dodecylamine (A). The 2-naphthol derivative can act as a proton donor due to excited state proton transfer (ESPT) and the 1,4-anthraquinone group can play the role of proton acceptor because of protonation of the reduced form if it is present. Absorption and emission spectra of LB films containing N and A were registered and separated into component bands. Individual absorption and emission peaks observed were assigned to given forms of chromophores. The behavior of different component bands reflects the state of anthraquinone dependent on proton concentration. A correlation of rate and efficiency of ESPT, with changes of the spectra of A, may be expected to yield information concerning the transport of protons from N to A. The influence of the donor-acceptor distance, sample humidity, film arrangement and the presence of protonophores (Gramicidin A) on proton transfer is studied. Our results indicate that the proton can be transported through the film but its concentration vanishes at the distance greater than 30 A. The efficiency of proton transfer depends strongly on water content, film structure and the presence of ion channels.

“…Details of the methodology of sensoric measurements were published elsewhere [14]. Relatively short response times and fair sensitivity at room temperatures, good reproducibility of results make these materials very promising candidates for gas sensing elements.…”

The synthesis, characterization, electropolymerization, electrical and sensing properties of LB films of mono-and dihexadecyl-bis(pyrrolyl)fluorene derivatives are reported. Different responses to different gases at various concentrations obtained for mono-and disubstituted derivatives of bis(pyrrolyl)fluorene make these materials a very good candidates for elements of gas sensing devices of the different type of an "artificial nose" or a neuronic network.
