Figure 2

TEM images of MIL-100(Fe) before and after modification with β-CDs derivatives: (a) unmodified MIL-100(Fe); (b) β-CD phosphate sodium salt purchased [27] modified MIL-100(Fe); (c) H9 modified MIL-100(Fe); (d) H10 modified MIL-100(Fe); (e) H11 modified MIL-100(Fe); (f) H12 modified MIL-100(Fe). Scale bar = 200 nm. These pictures indicate that after the introduction of CDs, the obtained organic–inorganic hybrid materials kept similar sizes and the rigid architectures were not affected.
