Compounds possessing the predicted unidirectional excitation conductivity and metal-organic nanostructures based on them are fabricated and investigated. The unidirectional excitation transfer in these compounds is confirmed. Computer simulations of electronic excitations passing through a functional macromolecule are carried out. Spectral investigations confirm that adenosine-thymidine sequences are electronic excitation traps in the nucleotide-containing molecular systems [ 1 ]. The formation of a chain of progressively lower energy levels in chromophores along the molecular system predicts not only the unidirectional neutral excitation transfer, but the unidirectional charge carrier current as well. Diode-like VAC-characteristics for the metal-organic systems of gold islands connected by π-electron-containing molecules are observed experimentally.
