Abstract. A series of mesoporous materials supported ionic liquids were prepared and tested as effective and practical catalysts for the synthesis of 2,4,5-triaryl-1H-imidazoles. The effects of type of catalysts, catalyst amount, and catalyst stability have also been investigated in detail, the catalyst Ti-SBA-15@ILTsO exhibited excellent activity in excellent yields of 92 % ~ 99 % with low catalyst amount at room temperature within 1 h. In addition, the supported ionic liquid can be easily recovered and reused for six times with satisfactory catalytic activity. Furthermore, a general synergetic catalytic mechanism for the reaction was proposed. Maybe this work employing Ti-SBA-15@ILTsO as highly efficient and stable catalyst for the synthesis of 2,4,5-triaryl-1H-imidazoles has potential commercial applications.   Resumen. Se prepararon y probaron una serie de materiales mesoporosos soportados con líquidos iónicos como catalizadores eficaces y prácticos para la síntesis de 2,4,5-triaryl-1H-imidazoles. También se investigaron en detalle los efectos del tipo de catalizadores, la cantidad de catalizador y la estabilidad del catalizador. El catalizador Ti-SBA-15@ILTsO mostró una excelente actividad con rendimientos excelentes del 92 % ~ 99% con una baja cantidad de catalizador a temperatura ambiente en 1 h. Además, el líquido iónico soportado puede recuperarse fácilmente y reutilizarse durante seis veces con una actividad catalítica satisfactoria. Por otro lado, se propuso un mecanismo catalítico sinérgico general para la reacción. Este trabajo que emplea Ti-SBA-15@ILTsO como catalizador altamente eficiente y estable para la síntesis de 2,4,5-triaril-1H-imidazoles puede tener aplicaciones potencialmente comerciales.
