Mesoporous hybrid materials containing two transition metal ions, one in the framework, the other in the channel pores

Mesoporous hybrid materials containing bridged metal–cyclam moieties in the silicate framework were synthesized by using triblock copolymer F127 as template and SiH3 as hydrolysable terminal groups; grafting of a metal–cyclam precursor in the channel pores led to materials containing two different strongly chelated transition metal ions in two steps.
