Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Mixed Langmuir—Blodgett films based on amphiphilic rhodamine dye molecules, hydrophobically modified polyampholyte, and stearic acid were prepared. The properties of monolayers at the water—air interface were studied. Three-component monolayers were found to be in a more condensed state than two-component ones. The absorption and fluorescence spectra of the films were recorded. Molecular aggregates with various structures could be produced by varying the concentrations of dye molecules, polymer, and stearic acid.
