    • MCM-41 was first dispersed in toluene by stirring. Water was added, resulting in immediate flocculation of the silica followed by dispersal over 2-3 h of stirring. Trichlorophenylsilane was then added and stirred overnight. The resulting solution was translucent in appearance. Isopropyl alcohol (IPA) was added and the solid filtered, washed with IPA and vacuum dried in an oven at 40 °C

    • Phenyl-SAMMS was added to a solution of BM, 1,3-BMMB or 1,4-BMMB dissolved in dichloromethane in a sealed vessel, placed on an orbital shaker and mixed overnight. After mixing, the vessel was uncapped and the solvent was evaporated followed by overnight vacuum drying at 40 °C. Chemisorbed ligand loadings are equal to either 2: 1 or 1: 1 phenyl moieties of the functionalized silica to BMMB molecules and are designated as low or high loading, respectively
