A layered organic/inorganic hybrid thin film, which consists of MoO3 with poly(5,6,7,8-tetrahydro-1-naphthylamine) (PTHNA), which is used as an aldehyde gas sensor, was investigated by X-ray diffraction (XRD) analysis and gas-sensing properties analysis. The (PTHNA)xMoO3 hybrid thin film shows distinct increasing resistance response to acetaldehyde and little response to formaldehyde in ppb level whereas typical organic/MoO3 hybrids show larger response to formaldehyde than to acetaldehyde or almost equal responses to formaldehyde and acetaldehyde in ppb level.
