Due to the high local concentration of substrates in confined space, porous solid Brensted acids have been extensively explored for efficient acid-catalyzed reaction. However, the porous structures with strong Brensted acids lack long-term stability due to chemical hydrolysis. Moreover, the products inhibition effect in confined rigid cavities severely obstructs subsequent catalysis. Here, tubular Brensted acid catalyst with unique recognition of protons was presented by self-assembly of pH-responsive aromatic amphiphiles. The responsive assembly could mechanically transfer hydrogen ions from low-concentration acidic solution into tubular defined pores, thereby producing effective catalytic activity for Mannich reactions in mildly acidic solution. Notably, the tubular catalyst unfolded into flat sheets upon addition of triethylamine for efficient release of products, which could be recovered by subsequent acidification and the catalytic activity still remained. Therefore, the porous Brensted acid with reversible assembly provides a new strategy for mass synthesis through increasing conversion times. & COPY; 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
