The structure and properties of monomolecular films based on N-octadecyl-3,4 : 9,10-perylene-bis(dicarboxydiimide)

Atomic force microscopy, ellipsometry, and piezoquartz microweighing techni ques were used to study the characteristics of N-octadecyl-3,4:9,10-perylen e-bis(dicarboxydiimide) monomolecular layers depending on the conditions of isolation and the nature of the substrate. The Langmuir-Blodgett him of th e compound was found to have an aggregation structure; film quality charact eristics (uniformity, absence of defects) were highest when monolayers were formed by X-type deposition on a hydrophilic surface. It was shown that at omic force microscopy thickness measurements for monomolecular layers of pe rylenetetracarboxylic acid derivatives should be performed taking into acco unt him elastic deformations under the action of the probe of the microscop e during scanning.
