Synthesis Of 2‐D polymer from semi‐amphiphilic Langmuir‐Blodgett (LB) films

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.
