In order to fabricate high sensi-tive gas sensor, chemical modification of porphyrin molecules by substituting both of long-chain hydrophorbic alkyloxyphenyl groups and hydrophilic hydroxyl group at their meso-po-sition could be made to meet the requirement for Langmuir-Blodgett film technique on the molecular structure. In this paper, a series of metalloporphyrin derivatives was designed and synthesized.展开更多
