Moreover, the products inhibition effect in confined rigid cavities severely obstructs subsequent catalysis. Here, tubular Bronsted acid catalyst with unique recognition of protons was presented by self-assembly of p H-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.
