- Аннотация: A new self-assembled and self-healing class of metalfree, recyclable, heterogeneous Brønsted acid catalysts has beendeveloped by the protonation of aniline derivatives (tetrakis(4-aminophenyl)methane, leuco-crystal violet, benzidine, and p-phenylenediamine) with aromatic sulfonic acids (tetrakis(phenyl-4-sulfonicacid)methane, and 2,6-naphthalenedisulfonic acid). As a result, fivethree-dimensional crystalline organic salts (F-1a, F-1b, F-1c, F-2,and F-3) were obtained, linked by hydrogen bonds and additionallystabilized by the opposite charges of the components. FrameworksF-2 and F-3 were prepared for the first time and characterized byelemental analysis, X-ray structural analysis (for F-2), thermogravimetry, SEM, and FTIR spectroscopy. The catalytic activities ofcrystalline organic salts F-1−3 have been explored in industrially important epoxide ring-opening and acetal formation reactions.The presence of encapsulated water inside frameworks F-1a and F-2 had an inhibitory effect on the performance of the catalysts. Xray diffraction analysis of hydrated and dehydrated samples of F-1a and F-2 indicated that water of crystallization served as a crosslinking agent, diminishing the substrate induced “breathing” affinities of the frameworks
