Résumé
Mesoporous hybrid materials containing bridged metal-cyclam moieties in the silicate framework were synthesized by using triblock copolymer F127 as template and SiH
3
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.
Mesoporous hybrid materials containing two strongly chelated transition metal ions, one in the framework, the other in the channel pores were prepared in two steps.
