Methyl triazone (4,4′,4″‐[l,3,5‐triazine‐2,4,6–triyItriimino]tris‐trimethyl benzoate) has been included in mesoporous MCM‐41 (Mobil's composition of matter‐41) silica, and its fluorescence emission has been compared in solution and in the solid state. Although inclusion does not affect significantly the absorption properties, a fluorescence emission shift and a behavior similar to the solid state has been observed by increasing the loading. It is believed that this observation reflects molecular aggregation inside the MCM‐41 channels. The potential of formulations of this type for sunscreen applications is discussed.
