摘　　要：A bolaform （BNC10） and single-headed （HNOA） amphiphilic Schiff bases containing naphthyl group were designed and their Langmuir-Blodgett films were investigated. It was found that both the LB films show acidichromism, i.e. a reversible color change upon alternatively exposing the films to HC1 and NH3 gases, respectively. It was further found that the bolaform Schiff bases film could trap NH3 gas during the acidichromic process.A bolaform （BNC10） and single-headed （HNOA） amphiphilic Schiff bases containing naphthyl group were designed and their Langmuir-Blodgett films were investigated.
