Monolayers and multilayers of anthraquinone derivatives containing long alkyl chains

摘要: Abstract Monolayers of seven anthraquinone derivatives containing one or two stearylamino-groups at different positions the ring system, spread air/water interface, have been studied by pressure-area isotherms and qualitative tests for rheological behaviors. Further, preparation multilayers these on solid surfaces has examined, using techniques vertical dipping horizontal lifting methods, thickness per single layer was measured optical method. From a consideration molecular models, probable orientations in films are discussed. It concluded that types orientation nuclei can be realized surface long-chain dyes, depending chemical modifications, such as variation numbers relative long substituent groups, also physical conditions deposition, pressures. is suggested with alkyl chains may provide model much interest spectroscopic researches dye aggregates.
