Zinc tetra-(p-trimethylaminophenyl)porphyrin (ZnTMAPP) and zinc 5,15-bis(4-trimethylaminophenyl)-10,20-bis(mesityl)porphyrin (ZnTMAPMP) will be discussed as dopants for isostructural tetraarylporphyrin molecular semiconductors. Solution phase electrochemistry in dimethylformamide reveals that the tetra-cation ZnTMAPP4+ 4I- can be reversibly reduced by four electrons to the neutral compound. Attempts to isolate the neutral compound by reduction of the tetra-cation with four equivalents of sodium amalgam were unsuccessful. A similar porphyrin di-cation ZnTMAPMP2+ 2I- was synthesized and solution phase electrochemistry of this compound in dimethylformamide reveals that the porphyrin undergoes two reversible one-electron reductions. The electrochemistry also shows that the neutral Zwitterion should be a strong enough reducing agent to act as a n-type dopant for its corresponding parent compound zinc 5,15-bis(4-tert-butylphenyl)-10,20-bis(mesityl)porphyrin. Isolation of the neutral n-type dopant has been difficult due to low solubility. Current work includes increasing the solubility of this neutral compound by first alkylating zinc 5,15-bis(4-dimethylaminophenyl)-10,20-bis(mesityl)porphyrin with octyl triflate rather than methyl iodide.
