Linear porphyrin arrays self-assembled by either hydrogen bonding or metal ion coordination self-organize into lipid bilayer membranes. The length of the transmembrane assemblies is decided both by the
thermodynamics of the intermolecular interactions within the supermolecule and by the dimension and physical chemical properties of the bilayer. Thus, the dimensions of the porphyrin assembly can self-adjust to the thickness of the bilayer. An aqueous electron acceptor is placed on one side of the membrane and an electron donor is placed on the other side. When illuminated with white light, substantial photocurrents are observed. Only the assembled structures produce to the photocurrent, as no current is observed from any of the component molecules. The superb work on the self-assembly of an outsized sort of supramolecular systems that have potential photonic, magnetic, catalytic, and analytical properties has been compatible by the event of physical methods to characterize these systems on the nanometer scale. The potential usefulness and functionality of those materials and systems has largely rested on proof of principle experiments, like those using scanning-probe tips to construct and evaluate the device. generally it's been recognized, albeit a burgeoning area of materials research, that these self-assembled systems will need to subsequently, or concomitantly, self-organize into hierarchical structures which will also form the interconnects to the macroscopic world. for several of those devices supported organic or hybrid inorganic-organic compounds, in analogy to biological systems, the first , secondary, tertiary, and quaternary levels of structural organization will got to be controlled. this work utilizes self-assembled porphyria arrays because the functional components of self-organizing photo gated conductors.
