| N4 macrocycles interest chemists because of their similarities to porphyrins. An example are the dibenzotetraaza[14]annulenes (DBTAAs). DBTAAs typically assume saddle-shaped conformations, allowing them to coordinate to a wider range of metal ions than porphyrins. The coordinating electrons point out of the plane of the nitrogens, making it unnecessary for the metal to fit within the coordination cavity. Benzoylations of DBTAA have been reported, resulting in molecules that are stable to demetalation via anhydrous hydrochloric acid. A monomeric DBTAA would be interesting because of its ability to be incorporated into a wide range of polymers, as well as for its capabilities as a metal scavenger and a catalyst. Potential applications can be seen specifically in HPLC columns and flow-through synthetic systems. We are currently exploring the synthesis of a DBTAA with benzoyl styrene functionalities so as to allow for its facile polymerization, and will present our results. |
