New Approaches to the Design and Synthesis of Molecular Wires for Biomedical and Nanotechnology Applications
Conjugated porphyrin oligomers exhibit remarkable properties, such as wire-like charge transport, ultrafast energy migration, nonlinear refraction and strong two-photon absorption. They are amazingly amenable to supramolecular control, and the coordination chemistry of the metal centers leads wide possibilities for template-directed synthesis.
This lecture will present the synthesis of π-conjugated nanorings which enter the size domain of a typical protein, such as the figure-of-eight complex shown below. Applications of related oligomers in molecular electronics and for probing electrical activity in neurons will also be discussed.
