| Abstract: The novel H2TNPP/TPA and H2TNPP/NaTP organic-inorganic hybrid nanocomposites [H2TNPP=tetrakis(4-N,N-diethylaminophenyl)porphyrin, TPA=the phosphotungstic acid and NaTP=sodium phosphotungstate] are fabricated by a simple QLS method. H-type molecular stacking mode with a tilted edge-on orientation of the H2TNPP has been formed in the hybrid films. The intermolecular face-to-face π-π interaction and film microstructures are effectively improved by introducing inorganic TPA and NaTP within the organic H2TNPP films, compared with the pure H2TNPP film. In particular, good film-conductivity, smaller grain size and large specific surface area of H2TNPP/NaTP hybrid film render it excellent sensing property for NO2 gas with the lowest detection limit of 0.094 mg·m-3 and highest sensitivity (43%) among the three kinds of films in room temperature, suggesting the great potential of semiconducting H2TNPP/NaTP organic-inorganic hybrid nanocomposites in the field of chemical sensors. The present result provides a new strategy to obtain high performance room-temperature gas sensors by the construction of organic/inorganic hybrid structure combined with a low-cost solution-based method. |
