  "abstract": "Using a coarse-grained model, we performed numerical simulations of the dynamics of linear molecular chains adsorbed on a flat substrate (on the surface of an h-BN crystal). It is shown that molecules containing benzene rings and hydroxyl groups in their structure can form stable hydrogen-bond chains OH$\\cdots$OH$\\cdots$OH. Such chains can be formed by phenol C$_6$H$_5$OH, 4-phenylphenol C$_6$H$_5$--C$_6$H$_4$OH, paracetamol CH$_3$C(O)NHC$_6$H$_4$OH, and 4-hydroxybenzanilide C$_6$H$_5$C(O)NHC$_6$H$_4$OH molecules. The dissociation of these chains occurs at temperatures above $T_1$=160, 210, 300, and 390K, respectively. Coating such molecular systems with a hexagonal boron nitride sheet (van der Waals encapsulation) significantly enhances their thermal stability. Such encapsulated molecular structures retain hydrogen-bond chains up to temperatures of $T_2$=510, 860, 600, and 1260K, respectively. The performed simulations allow us to conclude that chains of these molecules encapsulated by h-BN sheets can be used to create anhydrous proton-exchange membranes capable of operating at high temperatures. The most promising are chains of 4-hydroxybenzanilide molecules, since their hydrogen-bond chains possess the highest thermal stability.",
