1.1.試験デバイスの製造
半導体材料が、厚さ77nmの酸化シリコンの層上にエッチングされた、幅280nm、長さ4μm、厚さ16nmのエッチングシリコンナノワイヤーである、SOI上に電気デバイスを製作した。
官能基Rが4−エチニルベンジルである受容体をKemp三酸を用いて合成した。第1のステップで、塩化チオニル中の還流によってKemp三酸を無水物(生成物1)に変換する。残存塩化チオニルの蒸発後、ピリジン中で還流させながら生成物1を4−ヨードベンジルアミンと反応させ、次にトリメチルシリルジアゾメタンで処理する。園頭反応は、トリメチルシリル基で保護されたアルキンの導入を可能にする。分子3のLiAlH4による処理は、アミンおよびアルコール基を与えるように、それぞれイミドおよびエステル基を還元することができる。予想外に、シリル化基の脱保護が観察される。DFPによる処理で得られたKemp誘導体4の環化をNMR管内で行った。環化は完了する。
熱的ヒドロシリル化によって、試験デバイス上に受容体をグラフトする。濃硫酸と30%の過酸化水素水の3対1混合物で構成されるピラニア溶液でデバイスを洗浄し、次に1質量%のHF溶液で処理する。この活性化デバイスを、メシチレン中の受容体4の0.5mM溶液内で還流させる。
実施例1で得られたデバイスを用いて有機リン化合物の存在を検出した。このため、ジイソプロピルフルオロホスフェート蒸気(10ppm)を含むチャンバー内に1分間、本発明のデバイスを置いた。
