Counteranion Effects on the Incorporation of Photosystem I with Poly(3,4-ethylenedioxythiophene) (PEDOT).

ABSTRACT: Conductive polymers provide an effective interface for proteins, particularly in photovoltaic applications. The synthetic toolbox affords a variety of options in which to fine-tune protein-polymer properties toward better engineered materials. While prior work has shown compatibility between Poly(3,4-ethylenedioxythiophene) (PEDOT) and Photosystem I, a detailed study of counteranion effects with interfacing Photosystem I has yet to be performed. This study, which fills a significant gap in the field, involves the synthesis of PEDOT films with a variety of different potassium-based salts. Morphology, capacitance, and impedances all varied across the films when deposited in the presence of the different anions. These properties were evaluated independently before interfacing PSI.
