长脂肪碳链卟啉的合成及其LB膜的制备和气敏性质研究

1983年RuaudelTeixier［’j首先合成了两类具有长脂肪碳链的双亲性叶咐，其成膜性表明，它们可以形成良好的LB膜．M6hwald‘’修合成了不对称可成股叶琳，并对其膜结构和分子间作用进行了研究．Lecomte“‘等用钴叶琳和咪吐等衍生物以混合交替形式来模拟血红蛋白的吸氧及放氧过程，发现它可作为氧的载体．Tredgold［“报道了用铜、钻、镍、锰叶琳和无金属叶琳的LB膜元件对NO。、H。S和CO进行检测，发现铜叶琳对NO。有很高的敏感性，而对其它气体则无反应，显示出良好的选择性．本文在合成6种长脂肪碳链的双亲性叶琳化合物的基础上，…

Synthesis of Long Aliphatic Carbochain Porphyrins and Their LB Films and Study on Their Gas Sensitivity

Tetranicotinamidephenyl porphyrin(TNAPP) reacts with n-C16H33Br and n-C12H25 Br, respectively to yield the products tetra (N-hexadecyl nicotinamide phenyl) porphyrin bromide (THNAPPBr) and tetra-(N-dodecylnicotinamide phenyl ) porphyrin bromide. Its cobalt complex and zinc complex are also prepared. Those porphyrins and metal porphyrins have good film-forming properties. The gas sensitivity studies show that the six kinds of porphyrins are sensitive to NH3 and has a fine selectivity.
