SiC 4 units. The integral ratios were reproducible, with varying pulse delay times between 3 and 30 s, indicating that the 29 Si nuclei were sufficiently relaxed to give accurate integrals. Nitrogen isotherms demonstrated the ordered mesoporous nature of both PMD-2 and PMD-3 by showing typical type-IV isotherms. The BET surface areas were 775 m 2 g j1 (PMD-2) and 767 m 2 g j1 (PMD-3). The BJH analysis revealed a narrow pore size distribution with average pore sizes of 9.1 nm (PMD-2) and 8.2 nm
