Supramolecular Organization and Optical Properties of Langmuir-Schaefer Films of N,N'-di(3,5-Dimethylphenyl)diimide 1,1'-Binaphthyl-4,4',5,5',8,8'-Hexacarboxylic Acid

Abstract

Floating layers of N,N'-di(3,5-dimethylphenyl)diimide of 1,1'-binaphthyl-4,4',5,5',8,8'-hexacarboxylic acid (bis(3,5-(CH 3 ) 2 Ph)Cub) and Langmuir-Schaefer films of this compound on quartz and silicon substrates were ob-tained. By means of electron absorption spectroscopy it was found that only H-type aggregates contained in the film structure. The average size of the aggregates was determined using atomic force microscopy. It is shown that thiourea dioxide does not change the structure of the studied film, in contrast to its previously studied effect on the film formed by N,N'-di(4-chlorophenyl)diimide of 1,1'-binaphthyl-4,4',5,5',8,8'-hexacarboxylic acid containing aggregates of two types: J and H.
