title: Syntheses of normal, expanded, strapped and N-confused calixbenzophyrins from a single starting material.
abstract: The syntheses and spectral and structural characterization of hitherto unknown p-benzene incorporated normal, expanded, strapped and N-confused calixbenzophyrins are achieved; altogether five new macrocycles from a single starting material are reported. The binding studies of the strapped macrocycle revealed that the molecule is selective towards Fe(III) ions.
