"Syntheses of Porphyrinoids with Altered Core Structures"
on March 6, 2019 at 4:10pm in Neville Hall, Room 3
Porphyrinoids are well known for their biological functions (e.g., light harvesting, small molecule binding, electron transport, catalysis), and for their attractiveness in a host of fundamental investigations and applied studies. Progress in porphyrin chemistry has been aided by the ongoing development of synthetic methodology. Our primary efforts are directed towards the investigation of methods for the preparation of porphyrinoids that structurally differ from the familiar tetrapyrrolic structure of porphyrin. Such macrocycles display properties that are complementary to those of porphyrin. Key aspects of our work include examination of the choice of starting materials, exploration of the effect of reaction conditions on porphyrinoid yield, and the discovery of efficient, scalable reaction conditions (stepwise and one-flask). Our efforts towards systematic studies of a variety of reaction routes leading to intriguing porphyrinoids with altered core structures will be presented.
