In this work we investigated electronic properties and nature of intramolecular charge transfer as well as of intramolecular hydrogen bonding for autocomplexes of dinitroquinoline type. In these complexes an electron-accepting fragment was kept constant, while aromatic and N-containing heterocyclic electron-donating fragments were varied over a wade range. A regulation in the realization of intramolecular charge transfer as well as its nature have been determined . It was found under study that the molecules of these compounds have conformation in which two type of charge transfer transition have been revealed: through the conjugated bond system and by contact way through the space ( “contact charge transfer”). The analysis of the nature of hydrogen bonding shows that in molecules of these compounds it is realized resonanse intramolecular hydrogen bonding , including forking H-bonds.
