ИСТИНА

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.
