Project Overview

Syntheses of Pophyrinoids with Altered Core Structures

Faculty Sponsor

Rick Geier (




Porphyrinoids are well known for their biological functions (e.g., light harvesting, small molecule binding, electron transport, and catalysis as exemplified by heme, chlorophylls, and vitamin B12), and for their attractiveness in a host of  fundamental investigations (e.g., aromaticity, metal ion coordination, excited state energy transfer) and applied studies (e.g., molecular memory devices, dye sensitized solar cells, photodynamic cancer therapy). Progress in porphyrin chemistry is aided by the ongoing development of synthetic methodology. My research group’s primary efforts are directed towards the investigation of methods for the preparation of porphyrinoids that structurally differ from the prototypical tetrapyrrolic structure of porphyrin. Such macrocycles display properties that are complementary to those of porphyrin. Objectives of our work include determining the impact of the choice of starting materials, elucidating the interplay of reaction conditions, and discovering efficient, scalable reaction conditions.
