Synthesis and Supramolecular Chemistry of Novel Liquid Crystalline Crown Ether-Substituted Phthalocyanines: Toward Molecular Wires and Molecular Ionoelectronics

摘要: The synthesis of the metal-free and dihydroxysilicon derivatives tetrakis[4',5'-bis(decoxy)benzo-18-crown-6]phthalocyanine is described. phthalocyanine liquid crystalline exhibits a phase to mesophase transition at 148 degrees C. structures are determined by X-ray measurements. compound strongly aggregates in chloroform solution form gel. Electron micrographs show that this gel contains network fibers, each which built up parallel strands supermolecules having thickness one molecule length several micrometers. formed process self-assembly involving 10(4) molecules. They can be considered as being molecular cables, containing central electron wire, four ion channels, surrounding insulating hydrocarbon mantle. silicon derivative two axial hydroxy groups prevent from aggregating. This not crystalline. It forms stable monolayer air-water interface. In layer, planes oriented water surface. monolayers transferred onto glass substrates Y-type deposition. resulting Langmuir-Blodgett film bilayers slipped face-to-face dimers. capable binding alkali metal ions subphase, concluded surface area-surface pressure isotherms. constant for potassium has been analyzing isotherms function concentration ion. polymerized polysiloxane.
