A new series of sandwich-like lanthanide doping bis[2,3,9,10,16,17,23,24-octakis (octyloxy) phthalocyaninato] complexes Ln[Pc*]2 (Pc*=Pc(OC8H17)8, Ln=Sm, Pr, Er) were used as NO2 gas-sensing materials is described in the article. The gas-sensing films of Ln[Pc*]2 were prepared by Langmuir-Blodgett (LB) technique and the NO2 gas-sensing properties of Ln[Pc*]2 LB films were studied. The sensitive properties of Ln[Pc*]2 LB films to NO2 gas was monitored by the change of conductivity during gas exposure. Therein, Sm[Pc*]2 has the best sensitivity and responsivity to NO2 gas. The detecting range is from 0~100ppm, and the response and recovery time of 11-layer Sm[Pc*]2 LB film to 20ppm NO2 at room temperature is 16 s and 80 s, respectively. The thinner the film, the faster the response and recovery become. Recovery time in air is longer than that in pure N2.

Langmuir–Blodgett (LB) films of general organic semiconductor materials may be used as gas sensors because the conductivity depends on the presence of some gas species. Praseodymium bis [phthalocyaninato] complex-based LB films are very sensitive to the change of nitrogen dioxide (NO2) gas concentration. In the paper, a new kind of sandwich-like praseodymium bis[2,3,9,10,16,17,23,24-octakis (octyloxy) phthalocyaninato] complex Pr[Pc ]2 (Pc% Pc(OC8H17)8) was used as film-forming material. It is found that a mixture of Pr[Pc ]2 and octadecanol (OA) with 1:6 molar ratio formed an excellent material for the fabrication of gas-sensing LB film. The sensitive property of Pr[Pc ]2 LB films to NO2 gas was monitored by the change of resistance during gas exposure. The detecting range was from 0 to 100 ppm, and the response time of 11-layer Pr[Pc ]2 LB film to 20 ppm NO2 was 27 s at room temperature. Factors affecting gas-sensing properties of Pr[Pc ]2 LB films to NO2 gas such as temperature, number of film layers and processing conditions were also discussed in the paper.

Microsensor for nitrogen dioxide (NO2) fabricated by Langmuir–Boldgett (LB) films of Samarium bisw2,3,9,10,16,17,23,24-octakis (octyloxy)phthalocyaninatox complex SmwPc*x2 (Pc*sPc(OC8H17)8) and charge-flow transistor (CFT) are evaluated. Pure SmwPc*x and mixture of SmwPc*x and octadecanol (OA) deposited from both pure water and 10y4 M Cd2q subphases were 22 investigated. It is found that a mixture of 1:3 SmwPc*x2:OA forms an excellent material for the fabrication of gas-sensing LBfilm by studying the film-forming characteristic. Such novel microsensor has been fabricated by incorporating the multilayer LBfilm into the gate electrode of a metal-oxide-semiconductor field effect transistor, forming an array of CFT. On the application of a gate voltage (VGS), greater than the threshold voltage (VTH), a delay was observed in the response of the drain current. It is due to the time taken for the resistive gas-sensing film to charge up to VGS. This delay characteristic was found to depend on the concentration of NO2. Results are presented showing that the device can detect reversibly concentration of NO2 gas down to 5 ppm at room temperature.

Pm-e polyaniline (PAN) fihn, polyaniline and acetic acid (AA) mixed fihn, as well as PAN and polystyrenesalfonic acid (PSSA) composite fihn with various nmnber of layers were prepared by Langmuir Blodgett (LB) and selassembly (SA) techniques. These ultra thin fihns were characterized by ultraviolet visible (UV VIS) spectroscopy mid allipsometry, it is fomld tbat the tbickness of PAN based ultra thin fihns increases linearly with the increase of the number of fihn layers. The gas sensitivity of these ultra tbin fihns with vmious layers to NO2 was smdiedi it is fomld tbat pm-e polymliline fihns prepared by LB technique had good sensitivity to NO2, while SA fihns exhibited faster recovery property. The response time to NO2 mid the relative chmlge of resistmlce of ultra tbin fihns increased with the increase of the number of fihn layers. The response time of three layer PAN fihn prepared by LB technique to 20 ppm NO2 was about 10s, two layer SA fihn was about 8s. The mechmlism of sensitivity to NO2 of PAN based ultra thin fihns was also discussed.

A new kind of sandwich-like bisw2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyaninatox Praseodymium complex Pr(Pc*) 2 wPc*sPc(OC H) x is used as film-forming material. Pure Pr(Pc*) ultrathin film and Pr(Pc*) and octadecanol(OA) mixed 817822 ultrathin films were prepared by the Langmuir–Blodgett (LB) technique. Based on the conventional metal-oxide–semiconductor–field-effect transistor (MOSFET), a new chemical field-effect transistor (Chem FET) gas-sensing device was fabricated by depositing the Pr(Pc*) yOA (1:3 molar ratio) mixed LB film on the gate area of MOSFET replacing the gate metal. The sensitive 2 property of Pr(Pc*) yOA mixed LB film based ChemFET sensor to nitrogen dioxide (NO) gas is studied by the change of drain 22 current (1) during gas exposure. The Pr(Pc*) yOA mixed LB film ChemFET gas sensor can detect NO gas down to 5 ppm. ds 22 The qualities are attributed to amplification by the FET and the ordered nature of LB film. The mechanism of sensitivity of Pr(Pc*) yOA mixed LB film ChemFET to NO is also studied in the paper.

Electroactive nanocomposite ultrathin films of polyaniline PAN. and isopolymolybdic acid PMA. were fabricated by a novel molecular self-assembling process based on the alternate deposition of PAN and PMA from their dilute solutions. The process was based on doping-induced deposition effect of emeraldine base. The process was monitored by UVrVIS spectroscopy measurement. It was found that the conductivity of the PAN films is sensitive to humidity, NO2 and NH3. The technique may be used to fabricate chemical sensors and other molecular devices.

In this paper, submicrometer thin film of polypyrrole is prepared by electrolytic polymerization method. The best technological condition of preparing the submicrometer NH3-gas sensitive polypyrrole thin film is found by researching into the technological parameters of electrolytic polymerization. The NH3-gas sensitivity of polypyrrole is studied and the microstructure of this material is also discussed. Finally, adopting semiconductor theory, the NH3-gas sensitive mechanism of polypyrrole is extensively studied.
