Abstract
Presenting an electron-rich π system and an array of three pyrrolic nitrogen donors, linear tripyrrolic ligands are attractive platforms for metal coordination. While retaining several advantageous features of porphyrin-type ligands (e.g., tunable electronic structure, ligand-based one-electron redox chemistry), tripyrroles permit in-plane access to the metal center. The metal-binding properties of both synthetic and naturally occurring tripyrroles have been documented; however, this chemistry is still in its early stages and the full potential of this class of ligands has not yet come to fruition. Through a selection of examples, several areas of current and potential growth are described along with known hurdles that have emerged thus far.
