This work shows that a hollow and microporous metal‐free N,N′‐phenylenebis(salicylideneimine) (salphen) network (H‐MSN) can be engineered by Sonogashira coupling of [tetraiodo{di(Zn‐salphen)}] building blocks with 1,4‐diethynylbenzene in the presence of silica templates and by successive Zn and silica etching. Iron(III) ions could be incorporated into the H‐MSN to form hollow and microporous Fe–disalphen...
A hollow and microporous iron–disalphen network (H‐MFeSN) was engineered by template synthesis and by coordination of iron to a metal‐free disalphen network. H‐MFeSN shows not only a high surface area of 469 m2 g−1 and chemical stability, but also high catalytic activity and recyclability in the conversion of carbon dioxide to cyclic carbonates. More information can be found in the Communication by...
