Chiral porphyrin dimer with a macrocyclic cavity for intercalation of aromatic guests

Chemical Communications, 2011
Chiral diporphyrin receptor 1, which has a macrocyclic cavity to sandwich aromatic guest molecules via double π-π stacking interactions, enabled the naked-eye detection of an aromatic explosive as well as chiral discrimination in NMR.

Cavity-containing, backbone-rigidified foldamers and macrocycles

Chemical Communications, 2012
This Feature Article gives an account for a host of readily available foldamers and macrocycles with well-defined shapes and non-deformable cavities that appeared over the last decade. Efforts to create porous molecular structures have led to the establishment of an effective strategy for enforcing the folding of unnatural aromatic oligoamide strands ...

Structural control of metalloporphyrinogens by macrocycle modification: steric blocking of the macrocyclic cavity through trans-N,N′-dimethylation [PDF]

open access: yesDalton Transactions, 2003
Structural control of metalloporphyrinogens by macrocycle modification was discussed. Reactions of potassium metal with trans-N,N'-dimethyl-meso- octaethylporphyrinogen or meso-octaethyldioxaporphyronogen afford dipotassium complexes with one potassium ...

Tuning the size of macrocyclic cavities in trianglimine macrocycles

Organic & Biomolecular Chemistry, 2005
The synthesis of aromatic dicarboxaldehydes is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give trianglimine macrocycles. In particular, the scope and limitation of the reaction with regard to complete control of the cavity size of the macrocycles is discussed producing a total of ...
