Supramolecular systems derived from pyrrolo-tetrathiafulvalene building blocks

Abstract
The new pyrrolo[3,4-d]-TTF building blocks offers considerable scope as versatile building blocks for applications in macrocyclic, molecular, and supramolecular chemistry. Exemplified here by a receptor, such as the TTF-calix[4]pyrrole. The starting 2,5-unsubstituted pyrrolo-TTF can also be used for preparation of tetra- or mono TTF-annelated porphyrins. Key words. Tetrathiafulvalene - TTF - supramolecular systems - host guest interactions - anion complexation - pyrrolo[3,4-]tetrathiafulvalene - calix[4]pyrrole - tetrathiafulvalene annelated porphyrins.
