Synthesis of 2-D polymer from semi-amphiphilic Langmuir-Blodgett films

Abstract : Semi-amphiphilic monolayers formed via adsorption of tetraethynylpyridinium porphyrins to a dihexadecyl phosphate monolayer are allowed to react with ammoniacal silver nitrate or ammoniacal cuprous chloride, in order to form two-dimensional polymolecular species in which silver diacetylide groups or diacetylenic bonds are expected to link adjacent coplanar macrocycles. Evidences are given for the formation of these ultrathin two-dimensional networks.
