Sapphyrin Supramolecules through C−H⋅⋅⋅S and C−H⋅⋅⋅Se Hydrogen Bonds-First Structural Characterization of meso- Arylsapphyrins Bearing Heteroatoms

An unprecedented coupling reaction of heteroatom‐containing tripyrranes leads to the formation of core‐modified sapphyrins 1 and 2, which self‐assemble in the solid state to form supramolecular ladders. Weak C−H⋅⋅⋅S and C−H⋅⋅⋅Se hydrogen‐bonding interactions in addition to C−H⋅⋅⋅N hydrogen bonds are...

Summary:An unprecedented coupling reaction of heteroatom‐containing tripyrranes leads to the formation of core‐modified sapphyrins 1 and 2, which self‐assemble in the solid state to form supramolecular ladders. Weak C−H⋅⋅⋅S and C−H⋅⋅⋅Se hydrogen‐bonding interactions in addition to C−H⋅⋅⋅N hydrogen bonds are responsible for the observed structures.
