Device Operation

<p>Avoiding faradaic side reactions during the operation of electrochemical devices is important to enhance the device stability, to achieve low power consumption, and to prevent the formation of reactive side‑products. This is particularly important for bioelectronic devices which are designed to operate in biological systems. While redox‑active materials based on conducting and semiconducting polymers represent an exciting class of materials for bioelectronic devices, they are susceptible to electrochemical side‑reactions with molecular oxygen during device operation. We show that this electrochemical side reaction yields hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), a reactive side‑product, which may be harmful to the local biological environment and may also accelerate device degradation. We report a design strategy for the development of redox-active organic semiconductors based on donor-acceptor copolymers that prevent the formation of H<sub>2</sub>O<sub>2</sub> during device operation. This study elucidates the previously overlooked side-reactions between redox-active conjugated polymers and molecular oxygen in electrochemical devices for bioelectronics, which is critical for the operation of electrolyte‑gated devices in application-relevant environments.</p>

Dye Molecule

The dye-sensitized solar cell (DSSC) represents one of the most promising next-generation photovoltaic technologies. In addition, the DSSC manifold provides an exceptional platform to further appreciate photoinduced electron transfer and the fundamental features required for light-harvesting. The dye molecule is a key component in the DSSC and has achieved minor success utilizing both an organic and inorganic photosensitizers. DSSC’s show great promise owing to their inexpensive synthesis tunable optical and electrochemical properties, and a plethora of design possibilities. The typical anatomy of organic and inorganic DSSC dyes are comprised of a redox-active donor/chromophore (D) that is connected, through a conjugated linker (π), to an acceptor (A) capable of anchoring to titania (TiO2). Fine tuning each of these components can shift the absorption spectrum increasing the overall device efficiency. Boron-dipyrromethene (BODIPY) is an attractive moiety to integrate into DSSC dyes. BODIPY’s rigid organic framework should be able to improve dye stability while the high extinction coefficients of BODIPY based molecules have the potential to increase device performance. Herein, we explore the synthesis and physicochemical properties of BODIPY in an attempt to synthesize efficient DSSC dye molecules and efficient photovoltaic technologies.
