Atomic force microscopy, ellipsometry, and piezoquartz microweighing techniques were used to study the characteristic of N-octadecyl-3,4:9,10-perylene-bis(dicarboxydiimide) monomolecular layers depending on the conditions of isolation and the nature of substrate. The Langmuir-Blodgett film of the compound was found to have an aggregation structure; film quality characteristics (uniformity, absence of defects) were highest when monolayers were formed by X-type deposition on a hydrophobic surface. It was shown that atomic force microscopy thickness measurements for monomolecular layers of perylenetetracarboxylic acid derivatives should be performed taking into account film elastic deformations under the action of the probe of the microscope during scanning.
