Mesoporous material supported functionalized ionic liquids have been designed and synthesized, characterized and evaluated as novel heterogeneous catalysts for the Hantzsch reaction. The as‐fabricated catalysts show good performance in the Hantzsch synthesis of 1,4‐dihydropyridines under ambient conditions, especially the titanium incorporated mesoporous material supported ionic liquid Ti‐SBA‐15@IL‐BF 4 , based on a synergetic effect of titanium site of mesoporous material carrier and the acidic sites of ionic liquid. In addition, the heterogeneous catalyst offers simple operation for recovery and the recycling test showed that it could be reused for five times without significant loss of catalytic activity.
