The design, synthesis, and investigations of the special functional compounds containing several (up to 12)pi-electron systems are clone. The results of spectral investigations of the synthetic nucleotides-containing compounds are compared with the results obtained on DNA. The predicted processes of transfer of direct triplet electronic excitations in all the investigated functional compounds are proved. This fact gives the possibility to propose these compounds to be used for the design of nanoelectronic devices. The computer simulations of electronic excitations passing through an oligomer functional macromolecule taking into account the reverse exciton currents and the multipath excitation energy migration show these macromolecular compounds are perspective to be applied in nanoelectronics.
